CDBA240LR-HF

Overview

The CDBA240LR-HF is a Schottky barrier rectifier manufactured by Comchip Technology. It features a maximum repetitive peak reverse voltage of 40 V and an average forward rectified current of 2 A. The device utilizes a low-profile surface-mount package, specifically the DO-214AC (SMA) configuration. Key electrical characteristics include a low forward voltage drop to minimize power loss and high surge current capability for transient protection. The component is designed for ultra-high-speed switching applications and operates within a junction temperature range of -55°C to +150°C.

Feature Summary

• Low profile package design offering reduced physical dimensions compared to standard SOD-123 configurations
• Ultra-high-speed switching capability with low forward voltage drop for improved efficiency
• High surge current capability providing robust guarding against overvoltage transients
• Excellent thermal resistance and power dissipation characteristics ensuring stable operation

Applications

• DC-DC converter circuits requiring efficient rectification
• Power supply input/output stages in consumer electronics
• Free-wheeling diodes in inductive load switching applications
• Polarity protection circuits in battery-powered devices

Procurement Notes

Verify the specific suffix 'LR' against the official Comchip Technology datasheet to confirm package tolerance or marking variations. Ensure the ordering part number matches the required RoHS compliance status and packaging format. Cross-reference the manufacturer's latest revision history to validate pinout compatibility and electrical specifications before integration into production designs.

Selection Notes

Select this component when space constraints necessitate a low-profile SMA package while maintaining 2 A current handling. Evaluate the forward voltage drop at the expected operating current to ensure thermal management requirements are met. Confirm that the 40 V reverse voltage rating provides sufficient margin for the circuit's peak inverse voltage conditions during normal operation and transient events.
