Overview
The CDBA340L-G is a surface-mount Schottky barrier rectifier manufactured by Comchip Technology. It features a single diode configuration in a DO-214AC (SMA) package. The device supports a continuous forward current of 3 A and a maximum repetitive peak reverse voltage of 40 V. Key electrical characteristics include a low forward voltage of 500 mV at rated current, a non-repetitive peak forward surge current capability of 80 A, and a maximum reverse leakage current of 500 uA. It operates within a junction temperature range of -65°C to +125°C.
Feature Summary
- Low forward voltage design for improved efficiency
- High surge current handling capability
- RoHS compliant construction
Applications
- DC-DC converters
- Power supply circuits
- Reverse polarity protection
Procurement Notes
Verify the specific suffix 'G' indicates RoHS compliance as per manufacturer documentation. Confirm the package type matches DO-214AC requirements for your PCB layout. Ensure thermal management aligns with the specified operating temperature range during high-load conditions.
Selection Notes
Select this component when a compact SMD Schottky rectifier is required for low-voltage, high-efficiency applications. The 3 A rating suits moderate power levels, while the 40 V breakdown voltage provides adequate margin for standard 5 V or 12 V systems. Compare against similar SMA-packaged devices if space constraints are critical.
Part Context
This part belongs to Comchip's CDBA series of SMD Schottky Barrier Rectifiers. The series emphasizes low forward voltage drop characteristics suitable for modern power management designs. Comchip Technology specializes in various semiconductor components including diodes and MOSFETs, serving industrial and consumer electronics markets.
Replacement Considerations
Potential substitutes include other 3 A, 40 V Schottky rectifiers in the DO-214AC package from different manufacturers. Verify pinout compatibility and ensure equivalent forward voltage and leakage current specifications before substitution.
