CDBER00340-HF

Overview

The CDBER00340-HF is a Schottky barrier rectifier manufactured by Comchip Technology. It features a repetitive peak reverse voltage of 40V and an average forward current rating of 30mA. The device utilizes a small signal package suitable for surface mount applications. Key electrical characteristics include a maximum forward voltage of 370mV at 1mA and a reverse leakage current of 1µA at 40V. This component is designed for low-power switching and rectification tasks requiring fast response times.

Feature Summary

• Schottky barrier technology enables ultra-fast switching with minimal reverse recovery time
• Low forward voltage drop contributes to improved circuit efficiency
• Small signal package design optimizes board space for compact electronics

Applications

• Low power DC-DC converter output rectification
• Signal detection circuits in communication equipment
• Power supply freewheeling diodes for microcontrollers

Procurement Notes

Verify the specific package type and pinout configuration against your PCB footprint before ordering. Confirm that the 30mA current rating meets your application's peak load requirements. Ensure compatibility with your assembly process regarding the surface mount technology used for this component.

Selection Notes

Select this component when low forward voltage and fast switching are prioritized over high current handling. It is suitable for low-power applications where standard silicon rectifiers may introduce excessive voltage drops or slow recovery times. Evaluate thermal constraints as the small package has limited heat dissipation capabilities compared to larger packages.

Part Context

This part belongs to Comchip Technology's Schottky diode portfolio, specifically targeting small-signal applications. It complements other series like CDBAS and CDBU which offer higher current ratings. The CDBER00340-HF fills the niche for low-current, high-speed rectification needs in modern consumer and industrial electronics.

Replacement Considerations

Direct substitutes must match the 40V reverse voltage and 30mA forward current specifications. Verify that alternative Schottky diodes maintain similar forward voltage characteristics to ensure circuit performance consistency. Check package compatibility to avoid mechanical integration issues.
