CDBA340L-HF

Overview

The CDBA340L-HF is a surface-mount Schottky barrier rectifier manufactured by Comchip Technology. It features a single diode configuration in a DO-214AC (SMA) package. Key electrical parameters include a maximum repetitive peak reverse voltage of 40 V and an average forward rectified current of 3 A. The device exhibits a low maximum forward voltage of 0.45 V and a non-repetitive peak forward surge current capability of 125 A. Operating temperatures range from -50 °C to +150 °C junction temperature.

Feature Summary

Low forward voltage characteristic for reduced power loss
Low reverse leakage current for improved efficiency
Majority carrier conduction mechanism
Designed for high-efficiency surface-mount applications

Applications

Efficient DC-DC converters
Free-wheeling diodes in power supplies
Polarity protection circuits
Clamping diodes in electronic systems

Procurement Notes

Verify the specific suffix against official Comchip Technology documentation to confirm exact electrical tolerances and packaging variations. Ensure the component meets required RoHS compliance standards for the target application environment. Cross-reference datasheet revisions to validate parameter consistency before final procurement decisions.

Selection Notes

Select this component for designs requiring a 40 V blocking voltage with a 3 A continuous current rating in a compact SMA footprint. Consider the low forward voltage drop for thermal management in high-efficiency power conversion stages. Verify that the 125 A surge current rating aligns with the circuit's transient load requirements.

Part Context

This part belongs to the CDBA series of SMD Schottky Barrier Rectifiers from Comchip Technology. The series includes variants such as CDBA340LL-HF and CDBA340L-G, which share similar functional descriptions but may differ in specific packaging or regulatory suffixes. The manufacturer specializes in diode products including bridge rectifiers and TVS devices.
