Jan 10 2012 - Power [More Power Articles]

With 12 new 45V devices in three power package options that feature a wide range of current ratings from 10A to 40A – Vishay has expanded its offering of TMBS Trench MOS barrier Schottky rectifiers.

With extremely low forward voltage drops down to 0.51V typical at 20A, the rectifiers are optimized for use in solar cell junction boxes as bypass diodes for protection.

The devices released today include the single-chip V(B,F)T1045BP, V(B,F)T2045BP, V(B,F)T3045BP, and V(B,F)T4045BP. Each device is offered in the power TO-220AC, ITO-220AC, and TO-263AB packages.

All rectifiers feature a 200C maximum junction temperature in DC forward current without reverse bias (t ? 1 hour). The devices are compliant to RoHS Directive 2002/95/EC and WEEE 2002/96/EC.

The TO-263AB package offers a moisture sensitivity level (MSL) of 1, per J-STD-020, LF maximum peak of 245C. The TO-220AC and ITO-220AC packages feature solder bath temperatures of 275C maximum, 10s, per JESD 22-B106, and are halogen-free according to the IEC 61249-2-21 definition, says the company.
