Overview
The ACURB205-HF is a single fast recovery rectifier manufactured by Comchip Technology. It features a maximum repetitive peak reverse voltage of 500 V and an average forward rectified current of 2 A. The device utilizes the DO-214AA (SMA) surface-mount package. Key electrical characteristics include a maximum forward voltage of 1.3 V, a reverse leakage current of 5 uA, and a typical reverse recovery time of 75 ns. The component supports a maximum surge current of 50 A and operates within a junction temperature range of -55 °C to +150 °C.
Feature Summary
- Fast recovery performance with a typical reverse recovery time of 75 ns for efficient switching applications.
- High thermal stability capable of operating at junction temperatures up to +150 °C.
- Robust surge handling capability with a rated maximum non-repetitive peak forward surge current of 50 A.
Applications
- High-frequency DC-DC converter circuits
- Free-wheeling diode protection in power supplies
- General-purpose rectification in compact electronic devices
Procurement Notes
Verify the specific part number against official manufacturer documentation to confirm availability and compliance status. Ensure that the ordering suffix matches the required packaging format, such as cut tape or reel, as specified in the datasheet. Cross-reference the manufacturing date code and quality certifications with the supplier's declaration of conformity prior to procurement.
Selection Notes
Select this component when a 500 V blocking voltage and 2 A continuous current rating are required in a surface-mount SMA footprint. The fast recovery characteristic makes it suitable for high-frequency switching environments where low reverse recovery charge is critical. Compare specifications against standard recovery alternatives if switching speed is not a primary design constraint.
Part Context
This component belongs to the ACURB series of ultra-fast and fast recovery rectifiers from Comchip Technology. The series is designed for general-purpose rectification in space-constrained applications requiring reliable performance. The ACURB205-HF specifically addresses designs needing higher voltage ratings than lower-voltage variants while maintaining the compact form factor of the DO-214AA package.
