The STP11NK50Z is an N-channel 500 V, 0.48 ?, 10 A TO-220, TO-220FP, D2PAK Zener-protected SuperMESH? Power MOSFET. The well-known strip-based PowerMESH? layout of ST is greatly optimized to produce the SuperMESH? series. In addition to drastically reducing on-resistance, extra effort is taken to guarantee excellent dv/dt capability for the most demanding applications.
