12CWQ03FN

Overview

The Vishay 12CWQ03FN is a surface-mount Schottky rectifier featuring a dual anode common cathode configuration in a D-PAK (TO-252AA) package. It provides a maximum average forward current of 12 A per device and supports a peak repetitive reverse voltage of 30 V. The component exhibits a low forward voltage drop, rated at 0.47 V at 6 A and 0.55 V at 12 A. It operates within a junction temperature range of -55 °C to +150 °C and includes a guard ring structure for enhanced ruggedness.
