Product Summary

The 40CPQ045 is a center tap Schottky rectifier has been optimized for very low forward voltage drop, with moderate leakage. The proprietary barrier technology of the 40CPQ045 allows for reliable operation up to 150°C junction temperature. Typical applications of the 40CPQ045 are in switching power supplies, converters, free-wheeling diodes, and reverse battery protection.

Parametrics

40CPQ045 absolute maximum ratings: (1) Max. Average Forward Current IF (AV) : 40A (50% duty cycle @Tc = 120°C, rectangular wave form) ; (2) Max. Peak One Cycle Non-Repetitive Surge Current (Per Leg) IFSM: 3500A (5μs Sine or 3μs Rect. pulse) , 430A (10ms Sine or 6ms Rect. pulse) ; (3) Non-Repetitive Avalanche Energy (Per Leg) : 27mJ (Tj=25°C, IAS=4Amps, L=3.4mH) ; (4) Repetitive Avalanche Current IAR: 4A (Current decaying linearly to zero in 1μsec Frequency limited by Tj max. VA=1.5×VR typical.
