D-61 Package, 2 x 55 A

Fig. 5 - Maximum Allowable Case Temperature vs.

Average Forward Current (Per Leg)

(Per Leg)

Fig. 7 - Maximum Non-Repetitive Surge Current (Per Leg)

Fig. 8 - Unclamped Inductive Test Circuit

Note

(1) 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
