The Microsemi FST8145 is a high-current Schottky rectifier module designed for power conversion applications. It features a common cathode configuration with two diodes, each rated for 40A average forward current, providing a total package current rating of 80A. The module has a maximum reverse voltage of 45V and can withstand surge currents up to 800A per leg. The forward voltage is typically 530mV at 40A and 25°C.
With a maximum junction temperature of 150°C and a thermal resistance of 0.5°C/W from junction to case, the FST8145 is suitable for demanding thermal environments. The module is chassis mountable with screw terminals and has a typical weight of 8.4 grams. It is designed for fast switching applications with recovery times under 500ns.
The device is RoHS compliant and has an MSL rating of 1 with unlimited floor life. It is commonly used in power supplies, inverters, and motor drives where high efficiency and reliability are required.
Cross-reference parts include the industry equivalents 80CNQ045 and 84CNQ045. The FST8145 is manufactured by Microsemi Corporation, a leader in semiconductor solutions.
The FST8145 has a maximum peak reverse voltage of 45V.
