CDBM220-HF

Overview

The CDBM220-HF is a single-phase Schottky barrier rectifier manufactured by Comchip Technology. It features a 20V maximum repetitive reverse voltage and a 2A average forward rectified current capability. The device utilizes a low-profile SOD-123 surface-mount package, measuring approximately 2.9mm in length, 1.4mm in width, and 1.0mm in height. Key electrical specifications include a maximum forward voltage of 500mV at 2A and a maximum reverse leakage current of 10µA at 20V. It operates within a junction temperature range of -55°C to +150°C and supports a peak forward surge current of 30A.
