CDBC3150LR-HF

Overview

The CDBC3150LR-HF is a surface-mount Schottky barrier rectifier manufactured by Comchip Technology. It features a DO-214AB (SMC) package and utilizes silicon technology. The device supports a maximum repetitive reverse voltage of 150 V and an average forward rectified current of 3 A. Key electrical characteristics include a low forward voltage drop and minimal reverse leakage current, designed for high-efficiency power conversion applications.

Feature Summary

• Low forward voltage drop for enhanced energy efficiency
• Ultra-low reverse leakage current to minimize power loss
• High surge current capability for robust circuit protection

Applications

• DC-DC converters
• Power supply units
• Adapters and chargers

Procurement Notes

Verify the specific suffix 'LR' against the official datasheet to confirm it denotes the Low VF/Low IR variant rather than standard specifications. Ensure the DO-214AB footprint matches the design layout. Confirm RoHS compliance status with the manufacturer prior to finalizing procurement orders.

Selection Notes

Select this component when space-constrained designs require a 3 A Schottky rectifier in an SMC package. It is suitable for replacing standard rectifiers where reduced thermal dissipation and improved efficiency are critical. Verify that the 150 V rating aligns with the peak inverse voltage requirements of the target circuit topology.

Part Context

This part belongs to the CDBC series of Schottky barrier rectifiers from Comchip Technology. The series focuses on surface-mount solutions offering superior performance compared to traditional junction rectifiers. The LR designation typically indicates optimized parameters for low voltage drop and leakage within the standard 3 A SMC form factor.

Replacement Considerations

Direct substitutes include the CDBC3150-HF and SS315C-HF, provided they meet the specific low leakage requirements. Verify pinout compatibility and thermal resistance values before implementation.
