DESCRIPTION / APPLICATIONS
The VS-303CNQ... center tap Schottky rectifier module
series has been optimized for low reverse leakage at high
temperature. The proprietary barrier technology allows for
reliable operation up to 175 °C junction temperature. Typical
applications are in high current switching power supplies,
plating power supplies, UPS systems, converters,
freewheeling diodes, welding, and reverse battery
protection.

(1) Formula used: TC = TJ - (Pd + PdREV) x RthJC;
Pd = forward power loss = IF(AV) x VFM at (IF(AV)/D) (see fig. 6);
PdREV = inverse power loss = VR1 x IR (1 - D); IR at VR1 = 80 % rated VR
