SDT20100CT

Diode Arrays Overview

The SDT20100CT is a Trench Schottky rectifier manufactured by Diodes Incorporated, available in TO-220AB and ITO-220AB packages. It features a dual anode common cathode configuration with a peak repetitive reverse voltage of 100 V and an average rectified output current of 10 A per leg (20 A total). The maximum forward voltage drop is 0.71 V at +25°C for a 10 A load, while the maximum reverse leakage current is 80 µA under the same conditions. Non-repetitive peak forward surge current reaches 150 A, and the operating temperature range spans from -55°C to +150°C.
