DESCRIPTION  
The 8TQ...G Schottky rectifier 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 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 = 80 % rated VR
