CGRA4007-G

Single Diodes Overview

The CGRA4007-G is a general-purpose silicon rectifier manufactured by Comchip Technology, designed for surface-mount applications. It features a glass-passivated junction within a DO-214AC (SMA) package. The device supports a maximum repetitive peak reverse voltage of 1000 V and an average forward current of 1.0 A. Key electrical characteristics include a maximum non-repetitive peak forward surge current of 30 A, a maximum DC reverse current of 5 µA at rated blocking voltage, and a maximum instantaneous forward voltage of 1.1 V at 1.0 A. The component operates within a temperature range of -55 °C to +150 °C.

Single Diodes Feature Summary

• Glass passivated junction construction ensures high reliability and low leakage current
• DO-214AC molded plastic package with built-in strain relief for robust surface mount performance
• High surge current capability suitable for demanding power supply environments

Single Diodes Applications

• Surface mount general purpose rectification in consumer electronics
• Power supply input rectification stages
• DC-DC converter output rectification

Single Diodes Procurement Notes

Verify the specific manufacturer lot code and RoHS compliance status against the latest datasheet revision before integration. Confirm that the DO-214AC package dimensions align with your PCB footprint requirements. Ensure thermal management strategies account for the specified maximum junction temperature limits during operation.

Single Diodes Selection Notes

Select this component when a standard recovery rectifier is required in a compact surface-mount form factor. The 1000 V rating provides sufficient headroom for common AC line voltages. Compare the 1.1 V forward voltage drop against efficiency requirements relative to Schottky alternatives if lower loss is critical.

Single Diodes Part Context

This part belongs to the CGRA4001-G through CGRA4007-G series from Comchip Technology. The series covers reverse voltage ratings from 50 V to 1000 V while maintaining a consistent 1.0 A forward current capability. All variants share identical physical packaging and mechanical data, differing primarily in their breakdown voltage specifications.

Single Diodes Replacement Considerations

Direct functional equivalents include the CGRA4007-HF and other SMA-packaged 1A 1000V rectifiers such as the MBR1100 or SS1100 where reverse recovery characteristics permit substitution.
