Vishay Releases Industry-First Gen. 5.0 High-Performance 45-V and 100-V Schottky Diodes in D-Pak Package With Current Ratings From 6 A to 20 A
New Devices Built on Submicron Trench Technology Feature Maximum Junction Temperature to +175 °C, Very Low Typical Forward Voltage Drop Down to < 0.54 V, and Low Reverse Leakage Down to 3 mA
MALVERN, PENNSYLVANIA. — Feb. 18, 2009 — Vishay Intertechnology, Inc. (NYSE: VSH) today launched four new Gen. 5.0 high-performance 45-V and 100-V Schottky diodes that set a new standard in the industry by extending the D-Pak current capability up to 20 A. Built on submicron trench technology, the devices are suitable as stand-alone packages for high-efficiency, high-density solutions, as well as offering a cost-effective and compact replacement for the D2-Pak package. RBSOA is available for tight and cost-effective designs.
The 6CWT04FN, 10WT10FN, 20CWT10FN, and 20WT04FN offer a maximum junction temperature to +175 °C, extremely low forward voltage drop, and low reverse leakage, allowing designers to increase power density in automotive, solar energy, and other high-temperature applications. All four devices are also available in I-Pak versions.
The Schottky diodes released today feature maximum forward voltage drops at +125°C of < 0.54 V typical at 6 A and 20 A for the 45-V devices, and < 0.65 V at 10 A and 20 A for the 100-V devices. Reverse leakage at +125°C is 3 mA and 7 mA for the 45-V diodes and 4 mA for the 100-V diodes, with very tight parameter distribution. The devices offer optimized VF versus IR trade-off for increased system efficiency.
The diodes are optimized for ac-to-dc secondary rectification, flyback, buck and boost converters, half-bridge, reverse battery protection, freewheeling, dc-to-dc module, and solar photovoltaic bypass diode applications. Typical end products include high power density SMPS; adaptors for desktop PCs; servers; consumer electronics like PDPs, LCDs, and high-efficiency audio systems; and mobile electronics such as notebook computers, cell phones, and portable media players. The diodes are AEC-Q101 qualified for automotive drives and controls
A high and stable breakdown voltage of 57 V typical for the 45-V devices, and 118 V typical for the 100-V devices, accommodates voltage spikes and optimizes power density, which is increased in the diodes by 25 %. The devices feature 30 % increased ruggedness for reverse avalanche capability, with parts 100 % screened in avalanche, and negligible switching losses.
