HVP Now Offers up to 30 kV in Surface Mount SL Series!


HVP Introduces 20, 25, and 30 kV Surface Mount Diodes!
When we first introduced the SL series we knew we could get extreme voltages into surface mount diodes, now we’re proving it! With the introduction of three new diodes in our long surface mount package, the SL series moves to fulfill it’s mission of offering customers a complete range of high voltage diodes in a surface mount design.

Details for these additional parts are on our website now:

  • SLA20S – 20,000 Volt / 55 mA
  • SLA25S – 25,000 Volt / 50 mA
  • SLA30S – 30,000 Volt / 40 mA

There is still an extensive roadmap for these parts, including a new gull wing lead configuration, so keep an eye out for new standard products to be introduced in the coming months. Custom diodes in this surface mount package are available now for customers that have specific needs not met by the products immediately available. These parts are on the shelf and ready to be included in your new designs now!


DTI's NEW Optocoupler!


Dean Technology, Inc., today announced the introduction of a new high voltage optocoupler, the OPC10M. This 10 kV optical switch is able to variably control a high voltage
output up to 10,000 volts by adjusting a reference low voltage input, and is the first product in a new set of optical devices that DTI will be introducing in its HVCA line of products over the coming months.

Dean Technology’s optical switch products consist of a central diode and two or more LED drivers in a fully encapsulated and light-tight package. It is exceptionally space efficient, and the tight control of production methods will allow DTI to offer these parts at prices far better than competitive solutions.

“We’re starting off our optical switch line with a 10 kV part that should provide a perfect solution for many of the applications where this kind of device can be used,” said Lynn Roszel, Engineering Manager for Dean Technology. “For a long time, we’ve built custom solutions for customers using this technology and we’ve put all of that learning into the OPC10M. It is a very useful and stable optical switch that we’re very excited to have gotten into production.”

Dean Technology intends to release a wide range of new optical devices, starting with the OPC10M. A range of optical switches with higher voltages and power levels is planned, and a full line of optical diodes with clear encapsulation is already in the works. Custom parts for both of these types of products are being produced now and DTI has engineering resources ready to help with custom development for any customer’s needs. Full product details for the OPC10M, with example test circuits, are on the company’s website and the part is in stock and ready for purchase directly from Dean Technology or through any approved sales channel.


Important Update about Selenium Products

Dean Technology has developed an overseas partnership to produce selenium products. This partnership will enable the continued production of these products for many years to come, and helps to control and maintain the costs of these products to end customers.

Dean Technology, Inc. (DTI) has always had the great privilege of working very closely with our customers and partners in the design, development, production, and improvement of our products. This cooperation has led to great advances in the way that we run our business, produce our products, and the overall quality and reliability of every item we ship. The lessons we have learned from these advances constituted the core knowledge set utilized for designing our new corporate headquarters and production facility in Addison, Texas, into which we relocated during the spring of 2016.

One of the major goals in building out this new facility was to get all of our domestic U.S. production into a single space. We discovered early on that we would not be able to provide the same quality selenium products at the needed price point if we moved this production to the new facility, or it remained at our existing plant in Pennsylvania.

Dean Technology has always been committed to the continued production of products that others believe are technically obsolete. We do everything possible to continue production of all products for as long as any customer needs them. To this end, we broadened the focus of our search for a new home for the selenium production and were able to identify a partner facility overseas. This facility has been working on the production of selenium electronics for many years, and had both the knowledge and enthusiasm to learn how to make our products at the quality levels required. After an intellectual property transfer, transition, and education process of longer than two years, we have begun the initial production of our CKE line of selenium suppressors in this partner facility.

I am pleased to inform you that this transition has been an extreme success. Not only are we producing products of the same or superior quality, but we’ve been able to maintain, and in some cases even reduce, costs. We are now ready to begin transferring our customers to products made in this offshore partner facility.

As with any production process as complicated as these selenium suppressors, there will be some minor differences in the final products built in the new factory. To ensure that there is no confusion, we will be using a different color paint for the new products, as well has making minor alterations to the part numbers. For all of our standard, published part numbers currently in the SD series, we will transition to the SDI series (e.g., the current SD1543-8 will become SDI1543-8). All other part numbers will get a “S-“ prefix to identify the new part (e.g., the S06CA21AC will become S-S06CA21AC).

Another somewhat significant change will be the upper limit to the cell sizes that we can produce. The new facility has only been tooled to produce cell sizes up to 6” x 7.25”. We have not produced many parts using cells larger than this for some time, but we want to ensure that there is product continuity for all of our customers. To that end, we are able to create electrically equivalent parts using smaller cells in appropriate series and parallel configurations. These new designs will be done without cost to existing customers, and will provide the same performance as products built with the larger cells.

We understand that, for many customers, the transition to replacement products can be a challenging process. DTI is committed to helping all of our customers and partners with this transition in any way that we can. We will be stopping U.S.-based production of these parts in the fourth quarter of 2017, but all engineering and quality staff will continue to be a part of the Dean Technology team. Once a final date for domestic U.S. production is known, we will send a last time buy notice and will work with all of our customers to ensure they have the product they need to continue their own production at all times.

I honestly believe that we have done everything possible to prepare for this transition in a way that will mitigate as much risk as possible and minimize the impact on our valued customers. We know that nothing can be perfect though, and our technical, sales, and customer service teams will be ready to fully support all of our customers in the evaluation and transition to the new products.

If there are any questions or concerns about this production change, please do not hesitate to contact me directly. The most important goal of the entire DTI organization is the happiness of our customers, and I have no doubt that we will continue to meet that goal with the new production facility for our selenium suppressors.

On behalf of the entire team at Dean Technology, I thank you for your continued business and want to communicate our excitement about the great things to come.
