Vishay High Power Products Schottky Rectifier, 2 x 7.5 A
Fig. 5 - Maximum Allowable Case Temperature vs.
Average Forward Current
Fig. 6 - Forward Power Loss Characteristics
Fig. 7 - Maximum Non-Repetitive Surge Current (Per Leg)
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 = Rated VR
