DESCRIPTION
PRODUCT SUMMARY
The 20CJQ045PbF 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
