APT40DQ100BGVAO

Overview

The APT40DQ100BGVAO is a single ultra-fast soft recovery rectifier manufactured by Microchip Technology. It features a 1 kV reverse voltage rating and supports a continuous forward current of 40 A in a TO-247-2 through-hole package. Key electrical parameters include a maximum forward voltage of 3.08 V, a peak surge current capacity of 210 A, and a reverse leakage current of 100 uA. The device exhibits a recovery time of 315 ns and operates within a temperature range of -55 C to +175 C.

Feature Summary

• Ultra-fast soft recovery characteristics for efficient switching performance
• High thermal stability with an operating junction temperature up to 175 C
• Robust surge current handling capability for transient protection

Applications

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

Procurement Notes

Verify the specific suffix VAO against official Microchip documentation to confirm compliance with RoHS directives and any special packaging requirements. Confirm availability status directly with authorized distributors as stock levels fluctuate. Ensure the TO-247-2 footprint matches your PCB design constraints before finalizing procurement orders.

Selection Notes

Select this component when designing circuits requiring high-voltage isolation with fast switching speeds. The 1 kV rating suits medium-to-high voltage applications. Compare the 315 ns recovery time against system switching frequencies to ensure minimal reverse recovery losses. Verify that the 40 A continuous current meets the load requirements under expected thermal conditions.

Part Context

This part belongs to the APT series of discrete rectifiers from Microchip Technology, formerly known as Advanced Power Technology. The series focuses on high-performance silicon rectifiers for industrial and consumer electronics. The TO-247-2 package provides a balance of current handling and thermal dissipation suitable for through-hole mounting.

Replacement Considerations

Consult official substitution guides for equivalent parts with matching voltage and current ratings. Verify pin compatibility and thermal characteristics before replacing.
