DESCRIPTION
PRODUCT SUMMARY
The Schottky rectifier module has been optimized for
ultra low forward voltage drop specifically for the OR-ing
of parallel power supplies. The proprietary barrier
technology allows for reliable operation up to 125 °C
junction temperature. Typical applications are in parallel
switching power supplies, converters, reverse battery
protection, and redundant power subsystems.

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
