Rectifiers cut power losses, increase efficiency for commercial applications

Wed, 07/31/2013 - 2:40pm

LISTED UNDER:

Vishay Intertechnology expanded its offering of TMBS Trench MOS Barrier Schottky rectifiers with 12 new 45 V, 60 V, and 100 V devices that feature a wide range of current ratings from 6 A to 20 A. Optimized for use in commercial applications, the devices offer extremely low forward voltage drop in the surface-mount TO-252 (DPAK) package.

With their low forward voltage drop down to 0.34 V at 3 A, the nine dual-chip and three single-chip rectifiers released today 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. Ideal for automated placement, the devices are compliant to RoHS Directive 2011/65/EU and halogen-free according to JEDEC JS709A standards.
