The 40 W maximum power dissipation in the TO-220FP package means the designer must size the heatsink carefully if the device runs near its 14 A continuous rating; the isolated tab simplifies mounting but reduces thermal transfer compared to a standard TO-220 with a metal tab.
STMicroelectronics has classified the STP15NK50ZFP as obsolete.
A suitable replacement should match the 500 V drain-source voltage, 14 A continuous drain current, and TO-220 Full Pack (TO-220FP) package. The STP15NK50Z (non-isolated TO-220) is not a direct pin-compatible substitute due to the different package isolation. Evaluate other SuperMESH N-channel MOSFETs from STMicroelectronics with the same voltage, current, and TO-220FP package for a drop-in fit.
