Description/ Features
The Schottky rectifier module has been optimized for ultra low
forward voltage drop specifically for the OR-ing of parallel
power supplies. The proprietary barrier technology allows for
reliable operation up to 125 °C junction temperature. Typical
applications are in parallel switching power supplies, convert-
ers, reverse battery protection, and redundant power sub-
systems.
125°C TJ operation (VR < 5V)
Single diode configuration
Optimized for OR-ing applications
Ultra low forward voltage drop
Guard ring for enhanced ruggedness and long term
reliability
High purity, high temperature epoxy encapsulation for
enhanced mechanical strength and moisture resistance
Lead-Free ("PbF" suffix)

(2) Formula used: TC = TJ - (Pd + PdREV) x RthJC ;
Pd = Forward Power Loss = IF(AV) x VFM @ (IF(AV) / D) (see Fig. 6);
PdREV = Inverse Power Loss = VR1 x IR (1 - D); IR @ VR1 = 80% rated VR
