February 3, 2010 -- Vishay Intertechnology, Inc. today introduced six new single- and dual-chip 80-V TMBS Trench MOS Barrier Schottky rectifiers in four power package options that feature a wide range of current ratings from 10 A to 30 A.

The devices released today include the single-chip V(B,F,I)T1080S, V(B,F,I)T2080S, and V(B,F,I)T3080S, and the dual-chip V(B,F,I)T1080C, V(B,F,I)T2080C, and V(B,F,I)T3080C. Each device is offered in the power TO-220AB, ITO-220AB, TO-262AA, and TO-263AB packages.

With extremely low forward voltage drops down to 0.57 V typical and superior avalanche capability, the rectifiers reduce power loss and improve efficiency in freewheeling diodes and ac-to-dc and dc-to-dc converters in high-frequency power adaptors, switchmode power supplies (SMPS), desktop PCs, servers, and LCD TVs. The new rectifiers feature a maximum junction temperature of + 150 °C and are compliant to RoHS directive 2002/95/EC and WEEE 2002/96/EC. The TO-263AB package offers an MSL moisture sensitivity level of 1, per J-STD-020, LF maximum peak of 245 °C. The TO-220AB, ITO-220AB, and TO-262AA packages feature solder bath temperatures of 275 °C maximum, 10 s, per JESD 22-B106.
