Vishay Intros New Dual High-Voltage Schottky Rectifiers
Vishay Intertechnology Inc. (Malvern, PA) announced three new dual high-voltage Schottky rectifiers offering a 200 V reverse voltage, a 20 A forward current rating and a high maximum operating junction temperature of 175 °C. The new silicon-based devices are designed for secondary rectification of ac-dc and dc-dc converters with outputs up to 48 V, as well as power supplies of desktop and notebook PCs, servers, telecommunications exchangers, HDTVs, and other switch-mode power supply devices with high power outputs.
With a low typical forward voltage drop of 0.65 V at 10 A and 125 °C, small 1 mA maximum reverse leakage current at 125 °C, and high 290 A forward surge current per leg, the rectifiers have been optimized for 50 W to 250 W power supply applications. They also feature a large peak non-repetitive reverse surge energy of 20 mJ at 8 µs/20 µs per leg. All three devices feature a dual chip, common cathode configuration and a maximum operating junction temperature of 175 °C.
Package options are the TO-220AB (MBR20H200CT), isolated TO-220AB (MBRF20H200CT) and TO-262AA (MBRB20H200CT-1). Samples and production quantities of the new MBR20H200CT, MBRF20H200CT and MBRB20H200CT-1 Schottky rectifiers are available now, with lead times of six weeks for larger orders. Pricing is $800 per 1,000 units.
