Overview
The CDBC340-G is a surface-mount Schottky barrier rectifier manufactured by Comchip Technology. It features a single diode configuration in a DO-214AB (SMC) package. The device supports a maximum repetitive reverse voltage of 40V and an average forward current of 3A. Key electrical characteristics include a low forward voltage drop of 500mV at rated current, a peak forward surge current capability of 80A, and a maximum reverse leakage current of 500µA. It operates within a junction temperature range of -65°C to +125°C.
Feature Summary
- Soft switching characteristics for high-frequency efficiency
- Low forward voltage drop for reduced power loss
- High thermal stability for demanding environments
Applications
- High-temperature rectification circuits
- DC-DC converter output stages
- Power supply freewheeling applications
Procurement Notes
Verify the specific suffix '-G' confirms RoHS compliance and halogen-free status as per manufacturer specifications. Confirm the DO-214AB package footprint matches your PCB design requirements. Ensure the 40V rating aligns with your circuit's peak inverse voltage demands. Cross-reference the datasheet revision date to ensure compatibility with your design constraints.
Selection Notes
Select this component when a surface-mount solution is required for 40V applications. The 3A current rating suits moderate power levels. Consider the SMC package size for space-constrained designs. Compare forward voltage and leakage current against alternative brands if efficiency is critical. Verify thermal management capabilities for high ambient temperatures.
Part Context
This part belongs to Comchip Technology's CDBC series of Schottky rectifiers. It is designed for general-purpose rectification where speed and efficiency are priorities. The series offers various voltage and current ratings to cover diverse electronic needs. It complements other surface-mount diodes in the manufacturer's portfolio.
Replacement Considerations
Check for direct pin-compatible substitutes from other manufacturers offering similar 40V/3A SMC packages. Verify that any replacement maintains equivalent forward voltage and reverse leakage specifications. Ensure the alternative part meets the same thermal and mechanical standards.
