Overview
The CDBHA30100LR-HF is a low forward voltage Schottky barrier rectifier manufactured by Comchip Technology. It features a repetitive peak reverse voltage of 100V and an average forward rectified current rating of 30A. Designed for surface-mount applications, this silicon-based component utilizes the DO-214AB (SMA) package configuration. The device is engineered to provide efficient power conversion with reduced energy loss during operation.
Feature Summary
- Low forward voltage design minimizes conduction losses
- High current handling capability for robust performance
- Fast switching characteristics reduce recovery time
Applications
- DC-DC converter circuits
- Power supply freewheeling diodes
- Reverse polarity protection systems
Procurement Notes
Verify the specific datasheet revision and RoHS compliance status directly with Comchip Technology before procurement. Confirm that the DO-214AB package dimensions match your PCB footprint requirements. Ensure thermal management strategies account for the 30A current rating under expected operating conditions to maintain reliability.
Selection Notes
Select this component when high efficiency and fast switching are required in compact surface-mount designs. The 100V reverse voltage rating suits low-voltage DC bus applications. Compare thermal resistance specifications against alternative packages if space constraints allow for larger footprints offering better heat dissipation.
Part Context
This part belongs to Comchip's low VF Schottky barrier rectifier series, optimized for efficiency. It complements other models like the CDBHA10200LR-HF and CDBKA20120L-HF, which offer different current and voltage ratings within the same technology family for varied power management needs.
Replacement Considerations
Check for direct pin-compatible alternatives from Comchip or other manufacturers offering identical 30A/100V specifications in the SMA package. Verify forward voltage and reverse leakage current parameters to ensure equivalent circuit performance.
