Overview
The ACURB201-HF is a single ultra-fast recovery rectifier manufactured by Comchip Technology. It features a 50V repetitive peak reverse voltage and a 2A average forward current rating. The device utilizes a DO-214AA (SMB) surface-mount package. Key electrical characteristics include a maximum forward voltage of 1V, a reverse leakage current of 5uA, and a fast recovery time of 50ns. It supports a maximum surge current of 50A and operates at temperatures up to +150°C.
Feature Summary
- Ultra-fast recovery performance for high-speed switching applications
- Low forward voltage drop for improved efficiency
- Guardring structure provides overvoltage protection
- Silicon epitaxial planar chip construction
Applications
- High-frequency power supply circuits
- DC-DC converter output rectification
- Free-wheeling diode applications in inductive loads
- General purpose rectification in compact SMD designs
Procurement Notes
Verify the specific suffix against official Comchip documentation to confirm exact electrical tolerances and packaging options. Ensure the DO-214AA footprint matches your PCB layout requirements. Confirm RoHS compliance status through the latest manufacturer datasheet or PCN documents before finalizing procurement specifications.
Selection Notes
Select this component when low reverse leakage and rapid switching speeds are critical. The 50V rating suits low-voltage DC systems. Compare thermal derating curves if operating near the maximum junction temperature limit. Ensure the 2A continuous current rating aligns with the circuit's peak load demands without excessive heat generation.
Part Context
This part belongs to the CURB series of ultra-fast recovery rectifiers from Comchip Technology. It shares similar structural features with other members like the CURB201-G but may differ in specific suffix designations regarding packaging or testing standards. The SMB package allows for automated surface-mount assembly processes.
Replacement Considerations
Publicly confirmed substitute part numbers are not available in the provided source material. Cross-referencing requires consulting official manufacturer substitution guides or equivalent parameter matching from other vendors.
