Description/Features
The 31DQ.. axial leaded Schottky rectifier has been opti-
mized for very low forward voltage drop, with moderate
leakage. Typical applications are in switching power sup-
plies, converters, free-wheeling diodes, and reverse
battery protection.
Low profile, axial leaded outline
High purity, high temperature epoxy encapsulation for
enhanced mechanical strength and moisture resistance
Very low forward voltage drop
High frequency operation
Guard ring for enhanced ruggedness and long term
reliability

(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
