APT2X61D60J

Overview

The APT2X61D60J is a Fast Recovery Epitaxial Diode (FRED) power module manufactured by Microchip Technology. It features a Dual Parallel configuration housed in an ISOTOP SOT-227-4 package with screw mount installation. Key electrical specifications include a 600 V reverse voltage rating and a 60 A forward current per diode. The device exhibits a typical forward voltage of 1.6 V at rated current, a maximum surge current of 600 A, and a fast recovery time of 40 ns. Operating temperatures range from -55°C to +175°C junction temperature.

Feature Summary

• Dual parallel diode configuration within a single isolated module for efficient circuit design
• Fast recovery characteristics optimized for high-frequency switching applications
• High thermal performance enabled by the ISOTOP baseplate mounting style

Applications

• Switch mode power supplies
• Induction heating systems
• High frequency DC-DC converters

Procurement Notes

Verify the specific suffix 'J' against the official Microchip datasheet to confirm packaging and material compliance details. Ensure the ordering part number matches the required dual parallel configuration and voltage ratings. Confirm availability status directly with authorized distributors as production cycles may vary. Cross-reference the SOT-227-4 footprint requirements with your PCB or heatsink design prior to procurement.

Selection Notes

Select this component when a compact dual parallel rectifier solution is required for high-efficiency power conversion. The 40 ns recovery time makes it suitable for frequencies where standard diodes would incur excessive losses. Consider the 600 A surge capability for inrush protection scenarios. Evaluate the thermal resistance of the ISOTOP package relative to your system's cooling strategy to ensure operation within the 175°C junction limit.

Part Context

This component belongs to the APT2X series of discrete power diodes from Microchip Technology. The series utilizes epitaxial silicon technology to deliver robust performance in demanding power electronics environments. The ISOTOP packaging provides a standardized mechanical interface for easy integration into existing thermal management systems used across industrial and consumer power supply designs.

Replacement Considerations

Direct pin-to-pin replacements should be verified against the official Microchip cross-reference list. Alternative manufacturers may offer similar FRED modules in the SOT-227 form factor, but careful comparison of reverse recovery charge and thermal impedance is necessary to maintain system performance.
