CDBF00340

Overview

The CDBF00340 is a Schottky barrier rectifier manufactured by Comchip Technology. It features a silicon epitaxial planar chip with metal-silicon junction technology. The device is rated for a repetitive reverse voltage (VRRM) of 40 V and an average forward current (IF) of 30 mA. Key electrical parameters include a maximum forward voltage drop (VF) of 370 mV at the rated current, a peak forward surge current (IFSM) of 200 mA, and a maximum reverse leakage current (IR) of 1 µA. It operates within a temperature range of -40 °C to +125 °C.

Feature Summary

• Low forward voltage drop for high efficiency
• Ultra-high-speed switching capability
• Guarding against overvoltage protection

Applications

• Low profile surface mounted applications
• Power supply circuits requiring low loss
• High frequency rectification

Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm RoHS compliance status and check for obsolescence notices, as some sources indicate potential discontinuation. Ensure the specific ordering suffix matches the required package and termination specifications before finalizing procurement orders.

Selection Notes

Select this component for designs prioritizing low forward voltage and fast switching speeds in compact form factors. The SOD-323F package offers space optimization compared to standard packages. Evaluate thermal management requirements given the small footprint and ensure the operating temperature range aligns with system constraints.

Part Context

This part belongs to Comchip Technology's discrete semiconductor portfolio, specifically their Schottky diode line. The company specializes in surface-mount devices with flat chip manufacturing processes. This series utilizes gold-terminated leads to ensure solderability and reliability while meeting environmental standards.

Replacement Considerations

Check for direct substitutes within the same voltage and current ratings. Verify pinout compatibility and package dimensions (SOD-323F) to ensure mechanical fit. Confirm that alternative components meet the same thermal and electrical performance criteria.
