APT60D40LCTG

Overview

The APT60D40LCTG is a Fast Recovery Epitaxial Diode (FRED) manufactured by Microchip Technology. It features a dual common-cathode configuration housed in a TO-264-3 package. The device supports a maximum repetitive peak reverse voltage of 400 V and a continuous forward current of 60 A. Key electrical characteristics include a typical recovery time of 100 ns and a peak reverse recovery current of 180 A at specified test conditions.

Feature Summary

• Dual common-cathode architecture for efficient high-current power conversion applications
• Fast recovery epitaxial diode technology designed to minimize switching losses
• Robust thermal performance enabled by the large surface area of the TO-264 package

Applications

• High-frequency DC-DC converters
• Uninterruptible power supply (UPS) systems
• Motor drive circuits

Procurement Notes

Verify the specific suffix 'LCTG' against the official Microchip datasheet to confirm lead-free compliance and tube packaging details. Ensure that the TO-264-3 pinout matches the target PCB footprint, as variations exist within the broader product family. Cross-reference the manufacturer part number with authorized distributor catalogs to validate authenticity and traceability before finalizing procurement orders.

Selection Notes

Select this component when designing circuits requiring fast switching speeds and high current handling capabilities. The 400 V rating suits medium-voltage applications, while the 60 A capacity addresses substantial load requirements. Consider the thermal resistance of the TO-264 package for heat dissipation planning. Evaluate the reverse recovery charge specifications to ensure compatibility with the system's electromagnetic interference constraints and efficiency targets.

Part Context

This device belongs to the APT series of power rectifiers from Microchip Technology, formerly known as Advanced Power Technology. The series is characterized by high reliability and performance in demanding power electronics environments. The APT60D40LCTG specifically utilizes FRED technology to offer superior switching characteristics compared to standard recovery diodes, making it suitable for modern high-efficiency power supplies.

Replacement Considerations

Direct substitutes must match the 400 V/60 A rating, dual common-cathode configuration, and TO-264-3 package. Verify equivalent reverse recovery times and forward voltage drops to maintain circuit performance. Consult Microchip documentation for approved cross-references or updated revisions of the same package type.
