Single FETs, MOSFETs Procurement Notes

Verify the specific suffix FLLG against official Microchip documentation to confirm pinout and packaging details. Ensure compatibility with existing PCB footprints for the T-MAX-3 package. Confirm RoHS compliance status through the manufacturer's latest environmental declarations before integration into regulated products.

Single FETs, MOSFETs Selection Notes

Select this component when a 200 V rating and 100 A continuous current capacity are required in a through-hole format. Compare the 20 mOhm on-resistance against alternative packages like TO-264 if space constraints allow. Evaluate the 110 nC gate charge against available gate drive circuitry to ensure adequate switching speed without excessive driver stress.

Single FETs, MOSFETs Part Context

This part belongs to the APT series of FREDFET MOSFETs manufactured by Microchip Technology. It represents a discrete power transistor solution designed to replace older generation silicon devices in medium-voltage applications. The TO-247 MAX package provides superior thermal performance compared to standard TO-247 variants.

Single FETs, MOSFETs Replacement Considerations

Consult Microchip datasheets for direct replacements such as the APT20M16LFLLG, which offers lower on-resistance but requires verification of package and parameter compatibility.
