The ±25 V maximum gate-source rating provides headroom for gate-drive overshoot, but the recommended drive voltage for lowest Rds(on) is 10 V. ## Obsolete — sourcing the STP12NM50N today For new designs, a pin-compatible alternative from the same MDmesh family with similar voltage and current ratings should be evaluated — the STP12NM50N's 500 V, 11 A, TO-220 footprint is a common specification, and several active MDmesh II or MDmesh V parts fit that envelope.","metaTitle":"STP12NM50N MDmesh II N-Channel MOSFET, 500 V, 11 A, TO-220","metaDescription":"STP12NM50N N-channel MOSFET from STMicroelectronics MDmesh II series. 500 V drain-source, 11 A continuous, 380 mOhm Rds(on).

A functionally compatible replacement should match the 500 V drain-source, 11 A continuous drain, TO-220 package, and N-channel polarity. Several active STMicroelectronics MDmesh V parts in the same package and voltage class are worth evaluating.
