APT2X61DQ60J

Overview

The APT2X61DQ60J is a Fast Recovery Epitaxial Diode (FRED) discrete semiconductor 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 parameters include a maximum repetitive reverse voltage of 600 V and a continuous forward current of 60 A per diode. The device exhibits a typical forward voltage of 1.7 V at rated current, a maximum reverse leakage current of 25 uA, and a fast recovery time of 27 ns. It supports a maximum surge current of 600 A and operates within a junction temperature range of -55 C to +175 C.

Feature Summary

• Dual parallel configuration for efficient power rectification
• Fast recovery characteristics suitable for high-frequency switching applications
• ISOTOP thermal management design for effective heat dissipation
• High temperature stability for demanding industrial environments

Applications

• High frequency inverters
• Uninterruptible power supplies
• Switch mode power supplies
• Induction heating systems

Procurement Notes

Verify the specific suffix J indicates the standard tube packaging format when ordering. Confirm that the screw mount terminals match the mechanical footprint of the target heatsink assembly. Ensure the gate drive or circuit layout accommodates the specific parasitic inductance associated with the ISOTOP package structure. Cross-reference the latest datasheet revision to confirm pinout consistency before finalizing the bill of materials.

Selection Notes

Select this component when a dual parallel diode arrangement is required within a single compact module form factor. The 600 V rating suits medium voltage AC-DC conversion stages. The 27 ns recovery time makes it appropriate for frequencies exceeding standard soft recovery limits. Consider the 60 A continuous current capability against the expected thermal load and ambient conditions of the final enclosure design.

Part Context

This part belongs to the APT2X series of discrete semiconductor modules from Microchip Technology. The series utilizes silicon technology optimized for fast recovery applications. The ISOTOP family provides standardized mounting interfaces for various voltage and current ratings within the same physical envelope, simplifying board layout across different product generations.

Replacement Considerations

Direct replacements must match the 600 V, 60 A, dual parallel specification and SOT-227-4 package. Verify that any substitute maintains the 27 ns recovery time characteristic. Check for identical thermal resistance values to ensure compatibility with existing cooling solutions without redesigning the mechanical interface.
