NTSJ20U100CTG

Overview

The NTSJ20U100CTG is a dual Schottky rectifier utilizing trench-based technology. It features a 100 V peak repetitive reverse voltage rating and a 20 A average rectified forward current per device (10 A per diode). The maximum instantaneous forward voltage is 0.55 V at 5 A and 25°C, dropping to 0.50 V at 125°C. Thermal resistance from junction to case is 4.20 °C/W per diode. Operating junction temperature ranges from -40°C to +150°C.
