V20PWM45CHM3/I

Diode Arrays Overview

The V20PWM45CHM3/I is a high current density surface-mount Trench MOS Barrier Schottky (TMBS) rectifier manufactured by Vishay General Semiconductor. It features a SlimDPAK (TO-252AE) package with a typical height of 1.3 mm. The device provides a maximum repetitive peak reverse voltage (VRRM) of 45 V and a total maximum average forward rectified current (IF(AV)) of 20 A, split as 10 A per diode in its common cathode configuration. It achieves an ultra-low forward voltage drop of 0.39 V at IF = 5 A and 125 °C. The component is AEC-Q101 qualified for automotive applications.
