New Series about 3rd Generation Schottky Rectifier: Part2/5 - Products for Mobility Applications +++ Diotec at PCIM Europe 2019 +++ Declaration regarding California Proposition 65

Diotec's -3G Schottky Technology encompasses high power handling capability at small package outlines. It offers best state-of-the-art performance in the field of Schottky Rectifier. All our 3G Schottky diodes for Mobility Applications are available with AEC-Q101 rating.

Our new flagship for low power Schottky in SMD will be the SK34SMA-3G. It features a very low forward voltage and a low leakage current, and is thus perfectly suited for all kind of polarity protection or as an output rectifier in AC/DC or DC/DC converters.

Proof for its superior performance are these typical, application oriented parameters:
Vf < 0.32 V @ 1 A / 75°C
Ir < 120 µA @ 10 V / 75°C
Cj ~ 90 pF @ 4 V

Electronic systems for Mobility and Automotive embraces various applications such as powertrain, chassis control, body electronics, exterior and interior lighting or battery management of full electric vehicles. One of the common challenges in mobility electronic systems are the demand for power efficient, miniaturized and AEC-Q101 grade components made by innovative technology.

The SK34SMA-3G-AQ is currently under AEC-Q101 qualification; we expect completion within the 3rd quarter of this year.

Our actual -3G Schottky portfolio includes Rectifier Diodes with (Very) Low Forward Voltage Drop, reverse voltages from 20V to 45V and forward current ratings from 0.5A to 30A. A new flyer shows dedicated Schottky Diodes for Mobility Applications. If you prefer reading a hardcopy, you can order it here.

Main Features of -3G Schottky Technology:
- Very Low Forward Voltage
- Low Reverse Current
- High Power Dissipation
- High ESD Robustness
- Energy Savings
- Available with AEC-Q101 grading

In our May newsletter we will introduce -3G Schottky devices for Energy Applications.


PCIM Europe will take place from May 7 to 9 in Nuremberg. Diotec once again will be part of the world's leading exhibition and conference for power electronics, intelligent motion, renewable energy and energy management.

This year's topic of our booth will be our 3rd Generation Schottky Technology. You won't miss it, look out for large 3G Schottky logos. Stop by for a visit in hall 9 at booth 515 if you want to learn more about our 3G Schottky Technology. We might have the one or other nice giveaway waiting for you. Of course, you are also welcome if you just want to stop by for a cup of coffee.

Another entertaining fact on our booth will be our live demos. They are divided in our five market segments and applications: Lighting, Consumer, Mobility, Energy and Industrial. Every area will have a demo board on which the exhibition visitors can see and test by themselves how our diodes and rectifiers work.

Last but not least, we would like to invite you to our presentation "Shifting the Industry Standard on Schottky Diodes to a New Era: 3G Technology Reduces Power Losses by 20%" at the Exhibitor Forum in hall 7, stand 507 on Wednesday, May 8 from 1:20pm to 1:40pm.

The California Proposition 65 is "The Safe Drinking Water and Toxic Enforcement Act of 1986 by the State of California (USA)". Its goals are to protect drinking water sources from toxic substances that cause cancer and birth defects and to reduce or eliminate exposures to those chemicals in general by requiring warnings in advance of those exposures, for example in consumer products.

Diotec's products are not intended to be sold to end-users, as such we are not subject to California Proposition 65. However, as a Germany based company subject to the most strict European environmental legislations, we take our responsibility in the supply chain very serious. We inform therefore our customers with our Declaration about potential exposures by our components during or after use in their devices sold to their end-users.

Diotec at electronica in Munich +++ New products: SK54-3G and SK84-3G +++ Diotec Wall calendar for 2019 available

At our appearance at this year's electronica, there was a lot to see and a lot to try out for yourself! We were very happy about the numerous interested visitors and at the same time we were able to present our freshly printed AEC-Q101 Guide.

The SK54-3G and the SK84-3G were released and will now replace the SK54 and the SK84 respectively. These devices, from our 3rd generation Schottky Diodes, are of particular interest due to their improved low-voltage and lower reverse-current characteristics.

Once again this year we have sparred no effort and expense and prepared a wall calendar in our typical Diotec design for you, our customers. Unique in its design and for use in the office it is indispensable in having all your appointments visible at a single glance. If you would like to order your copy today, please send us your request direct via Mail.

Diotec at electronica in Munich +++ New products: 6.6SM8Z - series +++ AEC-Q101 Guide now available as printed brochure

One of the most frequently asked questions during this year's electronica was for sure regarding lead times. We collected actual market data and can proudly support you with some of the shortest delivery times in our field. Contact us directly and we will happily support you with our shortest possible lead times for your requested products. For the first time we have shown at our stand live demos of our parts in these Five Application Fields: Industrial, Consumer, Lighting, Automotive and Energy. You have been able to learn more about dedicated devices for these applications and even adjust the parameters of typical circuits to see the performance of the parts.

More news are available regarding various Diotec products. The SK34SMA-3G has been approved and will replace in a short time the existing SK34SMA. This 3rd Generation Schottky Diode with 3A/40V in SMA features a forward voltage of typically 390mV at 1A. It can be used e. g. as an output rectifier for switch mode power supplies with 5V. Even 10% less in forward voltage is offered by the SL34SMA-3G, which makes it ideally suited for polarity protection purposes. Both parts offer a low reverse leakage current of less than 100µA respectively 200µA.

Our TVS Diodes in SMA/B/C package have been qualified according to AEC-Q101. Their peak pulse power covers the entire range from 400W up to 5kW: P4SMAJ, P6SMBJ, 1.5SMCJ, 3.0SMCJ and 5.0SMCJ.

The new 6.6SM8Z - series offers an impressive 6.6kW at stand-off voltages of 10V up to 43V. It comes in the dedicated power package DO-218AB with a thermal resistance of only 0.9 K/W.

By the way...our AEC-Q101 Guide has been printed and was presented for the first time to public during electronica. It contains AEC-Q101qualified parts, which are not used just in automotive applications, but also others which require a special grade of qualification. Make sure to get your own exemplar of the printed version and directly order here.

Review: Diotec at PCIM 2018 +++ Growth within the Schottky diode family of the 3rd Generation +++ Demoboard: Soon available again

From 5 to 7 June we were exhibiting at PCIM in Nuremberg. Besides electronica, this is probably the most important event to our business. We are looking back on a very successful exhibition and look forward to the next one! Our exhibition calendar can be found directly here on our homepage.

As part of our trade fair appearance, we have not only been demonstrating some live demos, but of course also offered some great giveaways. Our Demoboard 3990 with Voltage Reference/Shunt Regulator and CLD were exhausted quite quickly, so that we need to produce already new ones. So if you were not able to get one directly at our booth, you can pre-order here.

Our third generation (-3G) Schottky diodes also attracted a lot of interest during PCIM. The newest member of this family is the PPS1545-3G in the only 1.1mm thin PowerSMD package. Having 15A/45V and comparable parameters than Trench-MOS devices, it needs much less space than diodes in a D-PAK. Thus, it offers a particularly space-saving alternative for your application.
