ACGRAT103L-HF

Overview

The ACGRAT103L-HF is a fast recovery rectifier diode manufactured by Comchip Technology, designed for surface-mount applications in the 2010 (5025 Metric) package. It features a maximum average forward rectified current of 1.0 A and a repetitive peak reverse voltage of 600 V. The device exhibits a fast recovery time of less than or equal to 500 ns and a low forward voltage drop characteristic. It is qualified under the AEC-Q101 standard for automotive reliability. Key electrical parameters include a maximum DC blocking voltage of 600 V, a maximum non-repetitive peak forward surge current capability, and a junction temperature range extending up to +175 °C.

Feature Summary

• AEC-Q101 qualified for automotive-grade reliability standards
• Fast recovery characteristics with reverse recovery time under 500 ns
• Low profile surface-mount packaging suitable for automated assembly
• High thermal stability with extended junction temperature rating

Applications

• Automotive power supply circuits
• General-purpose rectification in high-frequency switching applications
• DC-DC converter output stages
• Free-wheeling diodes in inductive load protection

Procurement Notes

Verify the specific datasheet revision and ordering suffixes when sourcing, as manufacturing updates may occur. Confirm that the received components match the AEC-Q101 qualification status required for your design. Ensure compatibility with the 2010 footprint dimensions during PCB layout finalization. Check for RoHS compliance documentation if environmental regulations apply to your region. Validate supplier authenticity through authorized distribution channels to prevent counterfeit parts.

Selection Notes

Select this component when a 600 V reverse voltage rating and 1 A continuous current capacity are required in a compact surface-mount form factor. The fast recovery speed makes it suitable for higher frequency operations compared to standard rectifiers. Consider the thermal management requirements associated with the small package size. Verify that the forward voltage drop meets the efficiency targets of the target circuit design.

Part Context

This part belongs to Comchip Technology's ACGRAT series of fast recovery rectifiers. The series is engineered for high-efficiency power conversion applications requiring rapid switching capabilities. The 'L' suffix typically denotes specific lead-free or low-profile variations within the product line. Comchip utilizes specialized flat chip technology for these devices to ensure robust performance and reliability in demanding electronic environments.

Replacement Considerations

Direct replacements must maintain the 600 V reverse voltage, 1 A forward current, and compatible 2010 package outline. Verify that substitute parts meet the same AEC-Q101 automotive qualification if used in vehicle systems. Ensure equivalent or better reverse recovery time specifications to avoid switching losses. Consult manufacturer cross-reference lists for officially confirmed equivalents.
