VB30120SG-E3/4W

Single Diodes Overview

VB30120SG-E3/4W is a high voltage Trench MOS Barrier Schottky rectifier manufactured by Vishay General Semiconductor. It features a single diode configuration in a TO-263AB (D2PAK) surface-mount package. The device supports a maximum repetitive peak reverse voltage of 120 V and an average forward rectified current of 30 A. Key electrical parameters include a peak forward surge current of 220 A, a maximum instantaneous forward voltage of 1.28 V at 30 A, and a peak repetitive reverse current of 500 μA at 120 V. Thermal resistance from junction to case is typically 1.6 °C/W.
