Vishay Intertechnology Inc. announced what it touts as the industry's first Schottky barrier rectifiers based on Trench MOS technology. Useful as a rectification circuit or OR-ing diode in redundant switchmode power supplies, or to replace synchronous rectification solutions, the five new TMBS devices feature one of the lowest forward voltage drop among Schottky rectifiers for their package types.

The first device on the market packaged in a TO-220AB case that is rated for 40A (2 x 20A) and 100V, said Vishay, the VTS40100CT is optimized for 100W to 300W high-frequency switchmode power supply applications. This device's ultra-low typical forward voltage drop of 0.375V at 5A and 125C reduces conduction power losses. The VTS40100CT can also improve OR-ing diode efficiency in the high-voltage output of redundant switchmode power supplies.

The new V40100P is also rated for 40A (2 x 20A) and 100V, with a TO-247AD case and an even lower typical forward voltage drop of 0.372V under the same conditions. That forward voltage drop is matched by the V50100P, which also has a TO-247AD case and a higher rating of 50A (2 x 25A), said the company.

The V30100S and VF30100S are both rated for 30A (1 x 30A) and 100V, with a typical forward voltage drop of 0.385V at 5A and 125C. The V30100S is packaged in a TO-220AB case, while the VF30100S is housed in a fully molded ITO-220AB case.
