APT1201R4BFLLG is listed in the Single FETs, MOSFETs range at ChipApex. The manufacturer field lists Microchip Technology. Its product description is MOSFET N-CH 1200V 9A TO247. Review the specifications below when checking this part for your BOM.
APT1201R4BFLLG is a single N-channel power FREDFET MOSFET manufactured by Microchip Technology. It features a 1200 V minimum drain-source breakdown voltage and a maximum continuous drain current of 9 A at case temperature. The device has a maximum on-resistance of 1.4 Ω and an avalanche energy rating of 1210 mJ. It is housed in a TO-247AD flange mount package with three terminals, where the case is connected to the drain.
Verify the specific suffix BFLLG against official Microchip documentation to confirm pinout and packaging details. Ensure compatibility with TO-247AD mounting hardware. Confirm RoHS compliance status through current datasheets as manufacturing processes may evolve.
Select this component for high-voltage applications requiring integrated freewheeling functionality. The 1.4 Ω on-resistance and 9 A current rating define its power handling limits. Consider the 1210 mJ avalanche energy rating for designs involving inductive load switching.
This part belongs to the Microsemi (now Microchip) APT series of power MOSFETs. These devices are designed for high-performance switching applications. The FREDFET technology combines MOSFET switching with fast recovery diode characteristics in a single package.
Consult official Microchip substitution guides for verified equivalents. Generic replacements may not match the specific avalanche energy or diode recovery characteristics.
