CDBV3-40A-G

Diode Arrays Overview

The CDBV3-40A-G is a dual series Schottky barrier rectifier manufactured by Comchip Technology. It features a silicon epitaxial planar chip construction with a metal-silicon junction, designed for surface-mount applications in the SOD-882 package. The device provides a repetitive peak reverse voltage (VRRM) of 40 V and an average forward current (IF) of 40 mA per diode. Key electrical characteristics include a maximum forward voltage drop (VF) of 1 V at rated current, a low reverse leakage current (IR) of 200 nA, and a non-repetitive peak forward surge current (IFSM) capability of 600 mA. It operates reliably within a junction temperature range of -55°C to +125°C.

Diode Arrays Feature Summary

• Dual series configuration integrates two independent Schottky diodes into a single compact surface-mount package.
• Low forward voltage drop minimizes power loss and enhances overall circuit efficiency during conduction.
• Ultra-fast switching speed reduces recovery time, making it suitable for high-frequency signal processing.
• Silicon epitaxial planar technology ensures robust performance with low thermal resistance.

Diode Arrays Applications

• DC-DC converter output rectification
• Power supply freewheeling circuits
• Signal detection and demodulation

Diode Arrays Procurement Notes

Verify the specific suffix 'A' against the official Comchip Technology datasheet to confirm pinout orientation and marking codes. Ensure the selected component matches the required SOD-882 footprint dimensions. Confirm RoHS compliance status directly from the manufacturer's documentation before finalizing procurement specifications.

Diode Arrays Selection Notes

Select this component when a dual Schottky configuration is required in a minimal footprint. The 40 mA rating suits low-power signal paths rather than high-current power delivery. Compare the 1 V forward voltage against alternatives if lower conduction losses are critical for the specific application design.
