ACGRA4003-HF

Overview

The ACGRA4003-HF is a general-purpose rectifier diode manufactured by Comchip Technology. It features a maximum repetitive peak reverse voltage of 200 V and an average forward rectified current of 1.0 A. The device utilizes the SMA (DO-214AC) surface-mount package. Key electrical characteristics include a maximum DC blocking voltage of 200 V, a forward current rating of 1 A, and a peak non-repetitive surge current capability typical for this package class. It operates within a junction temperature range of -55°C to +175°C.

Feature Summary

• Designed for surface mount applications with low forward voltage drop
• High surge current capability for robust protection against transient events
• Utilizes plastic encapsulation compliant with UL flammability standards

Applications

• General purpose rectification in consumer electronics
• Power supply input stages
• DC-DC converter circuits

Procurement Notes

Verify the specific suffix 'HF' indicates halogen-free compliance as per manufacturer documentation. Confirm the DO-214AC package dimensions match your PCB footprint requirements. Ensure the 200V reverse voltage rating exceeds the peak inverse voltage present in your circuit design to prevent breakdown. Check for RoHS directive compliance if required by your manufacturing standards.

Selection Notes

Select this component when a 1A current rating and 200V blocking voltage are sufficient for the load. The SMA package offers a compact solution for space-constrained designs compared to axial leads. Consider thermal management requirements for high-duty cycle applications, as the small surface area limits heat dissipation capabilities relative to larger packages.

Part Context

This part belongs to Comchip Technology's ACGRAT series of general-purpose rectifiers. These devices are silicon planar p-n junction diodes designed for high reliability. The series typically includes variants with different voltage ratings ranging from 50V to 1000V, all sharing the same 1A forward current capacity and SMA package form factor.

Replacement Considerations

Direct substitutes include other SMA-packaged 1A 200V rectifiers such as the 1N5822 or SS1P20, provided pinout and thermal characteristics are compatible. Verify that replacement parts meet the same reverse leakage and forward voltage specifications to ensure circuit performance parity.
