Reduce power loss with Vishay's new TMBS rectifiers

5th August 2013

Vishay has today announced an expansion of its TMBS Trench MOS Barrier Schottky rectifiers with the introduction of 12 new 45 V, 60 V, and 100 V devices, featuring a wide range of current ratings from 6 A to 20 A. Featuring extremely low forward voltage drop in a surface-mount TO-252 (DPAK) package, the new TMBS rectifiers are optimised for use in commercial applications.

The nine dual-chip and three single-chip rectifiers released today feature low forward voltage drop down to 0.34 V at 3 A. The new TMBS devices reduce power loss and improve efficiency in low-voltage, high-frequency DC/DC converters, switching power supplies, freewheeling diodes, OR-ring diodes, and reverse battery protection applications. Typical end products include set-top boxes, LED TV and computer power supplies, and ADSL modems.

The new rectifiers feature a maximum operation junction temperature of +150 °C and an MSL moisture sensitivity level of 1, per J-STD-020, LF maximum peak of 260 °C. Compliant to RoHS Directive 2011/65/EU and halogen-free according to JEDEC JS709A standards, the new TMBS devices are ideal for automated placement.
