STP21N90K5 ST Power MOSFET

The STP21N90K5 is an N-channel MDmesh K5 Power MOSFET from STMicroelectronics in TO-220 through-hole package, featuring 900V drain-source voltage and 14.5A continuous drain current for ultra-high voltage switching applications. For selection, verify built-in back-to-back Zener diodes for ESD protection, 100% avalanche tested for ruggedness, ultra-low gate charge for minimized switching losses, and operating junction temperature from -55°C to +150°C. Features include MDmesh K5 technology for industry's lowest RDS(on) x area, ultra-low gate charge for simplified drive requirements, Zener gate protection for enhanced reliability, and through-hole TO-220 package for robust mounting. Ideal for ultra-high voltage switching applications including offline power supplies for industrial equipment, high-voltage DC-DC converters, power factor correction (PFC) stages for three-phase applications, renewable energy inverters (solar strings), and any 900V high-power switching requiring low conduction losses with 14.5A current capability.
