CDBB340-HF

Overview

The CDBB340-HF is a Schottky barrier rectifier manufactured by Comchip Technology. It features a repetitive peak reverse voltage of 40 V and an average forward current rating of 5 A. The device utilizes the DO-214AA (SMB) surface-mount package configuration. Key electrical characteristics include a maximum forward voltage drop and low reverse leakage current, optimized for high-efficiency power conversion applications.

Feature Summary

• Schottky barrier construction enables ultra-high-speed switching capabilities
• Low forward voltage drop reduces power loss and improves efficiency
• Guarding against overvoltage transients in circuit protection roles

Applications

• DC-to-DC converter output rectification
• Power supply freewheeling diodes
• Reverse polarity protection circuits

Procurement Notes

Verify the specific ordering suffix to confirm compliance with environmental standards such as halogen-free or RoHS requirements. Confirm that the package type matches the target PCB footprint. Ensure the thermal management design accommodates the specified power dissipation limits under expected operating conditions.

Selection Notes

Select this component when a 40 V blocking capability and 5 A continuous current handling are required in a standard SMB package. Consider the low forward voltage characteristic for efficiency-critical designs. Evaluate thermal resistance parameters if operating near maximum current ratings in confined spaces.
