Notes:

1. Duty factor D = t1/ t2

2. Peak Tj = Pdm x ZthJC + Tc

Fig. 8 - Forward Power Loss Characteristics

Average Forward Current - IF(AV) (A)

(2) Formula used: T

C = TJ - (Pd + PdREV) x RthJC;

Pd = Forward Power Loss = I

F(AV) x VFM @ (IF(AV) / D)

(see Fig. 8);

REV = Inverse Power Loss = VR1 x IR (1 - D);

R @ VR1 = rated VR
