STP12NM50N

STP12NM50N Description

The STP12NM50N from STMicroelectronics is an N-channel 500V MOSFET belonging to the MDmesh™ II series, designed for high-efficiency power switching applications. With a continuous drain current (Id) of 11A (at 25°C case temperature) and a low on-resistance (Rds(on)) of 380mΩ at 10V gate drive, this device ensures minimal conduction losses. Its 500V drain-source voltage (Vdss) rating makes it suitable for high-voltage circuits, while the ±25V gate-source voltage (Vgs) tolerance provides robust gate control flexibility.
