Overview
The ACURB202-HF is a single-phase ultra-fast recovery rectifier manufactured by Comchip Technology. It features a reverse voltage rating of 100 V and an average forward current of 2 A. The device utilizes a DO-214AA (SMB) surface-mount package. Key electrical characteristics include a maximum forward voltage of 1 V at rated current, a reverse leakage current of 5 uA, and a typical reverse recovery time of 50 ns. It operates within a temperature range of -55°C to +150°C.
Feature Summary
- Ultra-fast recovery performance with 50 ns reverse recovery time for high-speed switching applications
- Low forward voltage drop of 1 V to minimize power loss and improve efficiency
- Guardring structure provides enhanced overvoltage protection capabilities
Applications
- High-frequency DC-DC converters
- Free-wheeling diodes in PWM circuits
- Reverse polarity protection in low-voltage systems
Procurement Notes
Verify the specific ordering suffix against official Comchip Technology documentation to ensure correct specifications. Confirm RoHS compliance status through manufacturer datasheets or environmental reports before integration into regulated assemblies. Cross-reference the DO-214AA package dimensions with PCB footprint libraries to prevent mechanical interference during assembly.
Selection Notes
Select this component when circuit requirements demand fast switching speeds combined with moderate current handling. The SMB package offers a balance between thermal dissipation and board space optimization compared to smaller SMD packages. Ensure the 100 V reverse voltage rating exceeds the peak inverse voltage present in the target application circuit under all operating conditions.
Part Context
This part belongs to Comchip Technology's ACURN series of ultra-fast recovery rectifiers. The series is designed for general-purpose high-efficiency rectification in surface-mount applications. Comchip specializes in discrete semiconductors, utilizing patented flat chip manufacturing processes to ensure reliability and consistent performance across their diode product lines.
Replacement Considerations
Consult official substitution guides for verified equivalents. Generic replacements must match the 2 A current rating, 100 V reverse voltage, and DO-214AA package form factor.
