APT2X31D30J

Overview

The APT2X31D30J is a discrete semiconductor module manufactured by Microchip Technology, classified under the ISOTOP family. It features a dual anti-parallel configuration of fast recovery diodes (FRED) housed in a SOT-227B package with screw mount installation. The device supports a maximum repetitive reverse voltage of 300 V and a continuous forward current of 30 A per leg. Key electrical parameters include a forward voltage of 1.2 V and a maximum operating temperature of +175°C. The component utilizes silicon technology and is supplied in tube packaging.

Feature Summary

• Dual anti-parallel configuration for efficient circuit integration
• Fast recovery diode technology optimized for high-speed switching applications
• ISOTOP package design facilitating robust thermal management and screw mounting

Applications

• High-frequency power conversion circuits
• Industrial motor drive systems
• Uninterruptible power supply (UPS) units

Procurement Notes

Verify the specific datasheet revision and product change notifications prior to procurement. Confirm that the SOT-227B mechanical dimensions align with the target PCB or heatsink layout. Ensure the supplier provides original manufacturer documentation to validate authenticity and traceability. Check for any recent updates regarding RoHS compliance status or material declarations.

Selection Notes

Select this component when a compact dual-diode solution is required for low-voltage, high-current applications. The 300V rating suits systems operating within this voltage range. Consider the 1.2V forward voltage drop for efficiency calculations. The screw-mount interface requires compatible hardware for secure installation and thermal contact.

Part Context

This part belongs to Microchip's ISOTOP series of discrete semiconductor modules. It shares the SOT-227B form factor with other variants in the line, such as the APT2X61DQ120J, but differs significantly in voltage and current ratings. The series is designed for industrial power electronics requiring reliable performance under high thermal stress.

Replacement Considerations

Direct substitutes may include the APT2X30D30J from the same manufacturer. Verify pin compatibility and thermal characteristics before swapping. Cross-reference with other manufacturers' SOT-227B dual FRED modules if Microchip inventory is unavailable.
