DESCRIPTION
The 50WQ04FNPbF surface mount Schottky rectifier has
been designed for applications requiring low forward drop
and small foot prints on PC board. Typical applications are in
disk drives, switching power supplies, converters,
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
