STD9N40M2 ST Power MOSFET

The STD9N40M2 is an N-channel MDmesh M2 Power MOSFET from STMicroelectronics in DPAK surface-mount package, featuring 400V drain-source voltage and 6.5A continuous drain current. For selection, verify maximum on-resistance at VGS=10V, gate charge for low switching losses, very low intrinsic capacitances for fast switching, excellent dv/dt capability, 100% avalanche tested for ruggedness, and operating junction temperature from -55°C to +150°C. Features include MDmesh M2 technology for best-in-class on-resistance per area, low gate charge for reduced drive requirements, very low output capacitance for improved efficiency, and Zener gate protection for enhanced reliability. Ideal for switching applications including offline power supplies (SMPS) for 400V DC input (e.g., PFC output or rectified 230V AC), LED lighting drivers, auxiliary power supplies in industrial equipment, power factor correction (PFC) stages, and any 400V power conversion requiring lower on-resistance compared to 600V devices for improved efficiency.
