DESCRIPTION
PRODUCT SUMMARY
The 20CJQ045 surface mount Schottky rectifier series has
been designed for applications requiring very low forward
drop and very small foot prints. Typical applications are in
portables, switching power supplies, converters, automotive
system, freewheeling diodes, battery charging, 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
