CDBC340LR-HF

Overview

The CDBC340LR-HF is a Schottky barrier rectifier manufactured by Comchip Technology. It features a 40V repetitive peak reverse voltage and a 3A average forward current rating. The device utilizes a DO-214AB (SMC) surface-mount package. Key electrical characteristics include a low forward voltage drop of 700mV at 3A and a maximum reverse leakage current of 20mA. It operates within a junction temperature range of -55°C to +150°C.

Feature Summary

• Low forward voltage for improved system efficiency
• High surge current capability
• Halogen-free construction

Applications

• General purpose rectification in power supplies
• DC-DC converter output stages
• Free-wheeling diodes in inductive load circuits

Procurement Notes

Verify the specific suffix 'LR' against the official datasheet to confirm package and marking variations. Ensure the component meets RoHS compliance requirements for your assembly process. Cross-reference the Mouser number 750-CDBC340LR-HF for accurate distributor identification and documentation access.

Selection Notes
