DESCRIPTION
PRODUCT SUMMARY
This center tap Schottky rectifier has been optimized for very
low forward voltage drop, with moderate leakage. The
proprietary barrier technology allows for reliable operation up
to 150 °C junction temperature. Typical applications are in
switching power supplies, converters, freewheeling diodes,
and reverse battery protection.

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 = 10 V
