45V and 100V schottky diodes in D-Pak package with current rating 6- 20 A

Vishay Intertechnology launched four new Gen.5.0, Schottky diodes with 45V and 100V voltage rating in D-Pak package and current capability up to 20 A. Built on submicron trench technology, the devices are suitable as stand-alone packages for high-density solutions, as well as offering a compact replacement for the D2-Pak package.
The 6CWT04FN, 10WT10FN, 20CWT10FN, and 20WT04FN offer a maximum junction temperature to +175°C, forward voltage drop, and low reverse leakage, allowing designers to increase power density in automotive, solar energy, and other high-temperature applications.

Some of the key features are:

1. Feature maximum forward voltage drops at +125°C of < 0.54 V typical at 6A and 20A for the 45V devices, and < 0.65 V at 10 A and 20 A for the 100V devices.
2. Reverse leakage at +125°C is 3 mA and 7 mA for the 45V diodes and 4 mA for the 100V diodes, with very tight parameter distribution.
3. The devices offer optimized VF versus IR trade-off for increased system efficiency.
4. The diodes are optimized for ac-to-dc secondary rectification, fly-back, buck and boost converters, half-bridge, reverse battery protection, freewheeling, dc-to-dc module, and solar photovoltaic bypass diode applications.
5. Typical end products include high power density SMPS; adaptors for desktop PCs; servers; consumer electronics like PDPs, LCDs, and audio systems; and mobile electronics such as notebook computers, cell phones, and portable media players.
6. The diodes are AEC-Q101 qualified for automotive drives and controls.

7. A breakdown voltage of 57V typical for the 45V devices, and 118V typical for the 100V devices, accommodates voltage spikes and optimizes power density.

Availability: Samples and production quantities of the new Schottky diodes are available now, with lead times of six to eight weeks for larger orders.

Package:
1. D-Pak package
2. All four devices are also available in I-Pak versions
