SBRT40V100CT

Diode Arrays Overview

The SBRT40V100CT is a dual common cathode Trench Super Barrier Rectifier manufactured by Diodes Incorporated. It provides a peak repetitive reverse voltage (VRRM) of 100 V and an average rectified output current (IO) of 20 A per leg, totaling 40 A. The forward voltage drop (VF) reaches a maximum of 0.73 V at 20 A and +25°C. Reverse leakage current (IR) is limited to 0.3 mA at +25°C and 45 mA at +125°C when VR equals 100 V. The non-repetitive peak forward surge current (IFSM) is rated at 180 A. Operating junction temperature ranges from -55°C to +150°C.

Diode Arrays Feature Summary
