ACURB207-HF

Overview

The ACURB207-HF is a surface-mount ultra-fast recovery rectifier manufactured by Comchip Technology. It features a DO-214AA (SMB) package and supports a maximum repetitive reverse voltage of 1000 V with an average forward rectified current of 2 A. The device exhibits a low forward voltage drop of 1.3 V and a rapid reverse recovery time of 50 ns, ensuring efficient switching performance. It operates within a junction temperature range of -55°C to +150°C and includes a peak forward surge current rating of 50 A for transient protection.

Feature Summary

• Ultra-fast recovery characteristics enable high-speed switching applications
• Low forward voltage drop contributes to reduced power loss and improved efficiency
• Robust thermal management capability with extended operating temperature range up to 150°C

Applications

• High-frequency DC-DC converters

Procurement Notes

Verify the specific datasheet revision and RoHS compliance status directly with Comchip Technology or authorized distributors before integration. Confirm that the DO-214AA footprint matches your PCB design requirements. Ensure that thermal management strategies account for the specified maximum junction temperature limits under expected load conditions.

Selection Notes

Select this component when high-voltage blocking capability and fast switching speeds are required in a compact surface-mount form factor. Compare the 50 ns recovery time against slower standard recovery alternatives if minimizing switching losses is critical. Evaluate the 1000 V rating against system voltage spikes to ensure adequate safety margins.
