Vishay High Power Products

Schottky Rectifier, 10 A

Fig. 5 - Maximum Allowable Case Temperature vs.

Average Forward Current

Fig. 6 - Forward Power Loss Characteristics

Fig. 7 - Maximum Non-Repetitive Surge Current

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
