Vishay Releases 5th Generation Family Of 100-V Schottky Diodes
Vishay Intertechnology, Inc. launched a new high-performance Schottky Diode Gen 5.0 silicon platform with 8 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 (>115V) 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 0.55V at 8A to 0.61V at 30A, and extremely low typical reverse leakage from 1mA to 5.5mA 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.
Samples and production quantities of the new 5th generation family of Schottky diodes are available now, with lead times of eight to 10 weeks for larger orders. Distribution pricing for U.S. delivery ranges from $0.32 to $1.45 per piece.
