STMicroelectronics STP20NK50Z/STW20NK50Z N-Channel Power MOSFET Datasheet
This document provides technical specifications for the STP20NK50Z (TO-220 package) and STW20NK50Z (TO-247 package), which are N-channel 500V Super MESH™ Power MOSFETs. These devices feature extremely high dv/dt capability, gate-source zener protection, and are designed for high current, high speed switching applications such as off-line power supplies and PFC circuits.
The datasheet includes absolute maximum ratings, electrical characteristics covering on/off states and dynamic parameters like capacitance and switching times, avalanche characteristics, and detailed mechanical data for both TO-220 and TO-247 packages.
