STW12NK90Z 900V N-Channel MOSFET

STW12NK90Z 900V N-Channel MOSFET – TO-247 Package

STW12NK90Z is a 900V N-Channel MOSFET designed for high-voltage power electronics, supporting up to 11A continuous current with 230W maximum power dissipation. It utilizes SuperMESH™ technology for reduced RDS(on) and improved switching efficiency, making it suitable for applications such as SMPS, industrial drives, energy storage systems, and solar inverters.

This device offers low gate charge and excellent dv/dt handling, enabling high-speed switching with minimal losses. Its TO-247 package provides efficient thermal performance and enhanced durability under elevated temperatures. A built-in Zener diode at the gate ensures added protection from voltage spikes and transient events.

STW12NK90Z is ideal for engineers developing circuits that demand high-voltage endurance, low conduction loss, and fast switching in robust environments including UPS systems, motor controls, telecom supplies, and renewable energy infrastructure.
