Vishay Releases 5th Generation Family of High-Performance 100-V Schottky Diodes That Offer Tj Max of +175 °C For High-Temperature Applications
Nine New Devices Feature Very Low Typical Forward Voltage Drop From 0.55 V at 8 A to 0.61V at 30 A, Extremely Low Typical Reverse Leakage From 1 mA to 5.5 mA at 125 °C , and an Overall 30 % Increase in Power Density
MALVERN, PENNSYLVANIA — Jan. 30, 2008 — Vishay Intertechnology, Inc. (NYSE: VSH) today launched a new high-performance Schottky Diode Gen 5.0 silicon platform with eight new devices offering low forward voltage drop, low reverse leakage, and a high maximum junction temperature for high-temperature applications.
Featuring submicron trench technology, Vishay’s new family of Schottky diodes offers a maximum junction temperature of +175 °C, making them suitable for automotive and other high-temperature applications. The devices are offered in small RoHS-compliant packages for improved cost-to-power ratios, with a reverse biased safe operating area (RBSOA) available for tight and cost-effective designs. A high and stable breakdown voltage (>115 V) accommodates voltage spikes and optimizes power density, which is increased in the diodes by 30 % compared with previous-generation products. Even so, the new devices are priced up to 10% lower than Vishay’s planar Gen 3.1 and the planar Gen 2.0 devices.
The new diodes are optimized for ac-to-dc, secondary rectification, flyback, buck and boost converters, half-bridge, reverse battery protection, freewheeling, class-D amplifiers, and dc-to-dc module applications. Typical end products include high power density SMPS; adaptors for desktop PCs; servers; automotive drives and controls; telecom networks; consumer electronics like PDPs, LCDs, and high-efficiency audio systems; and mobile electronics such as notebook computers, cell phones, and portable media players.
The devices offer a very low typical forward voltage drop from 0.55 V at 8 A to 0.61 V at 30 A, and extremely low typical reverse leakage from 1 mA to 5.5 mA at 125 °C, with very tight parameter distribution. They feature increased ruggedness for reverse avalanche capability, with parts 100 % screened in avalanche, and negligible switching losses.
