Equivalent & Substitute Parts Reference: APT41M80L

Part Overview

APT41M80L is an N-Channel MOSFET designed for high-voltage and high-current applications in the Transistors, FETs, MOSFETs category. Featuring a drain-to-source voltage (Vdss) of 800 V and a continuous drain current (Id) of 43A (Tc), this device offers a robust solution for power switching and control. The part is currently active, ROHS3 compliant, and REACH unaffected, indicating wide availability and regulatory acceptance. Identifying substitute models is necessary to address supply constraints, design alternate sourcing, or ensure continued production when inventory fluctuations arise.
