STW18N65M5

STW18N65M5 Description

The STW18N65M5 from STMicroelectronics is a high-performance N-channel MOSFET designed for demanding power applications. Built using advanced MDmesh™ V technology, it offers a robust 650V drain-to-source voltage (Vdss) rating and a continuous drain current (Id) of 15A (Tc). With an Rds(on) as low as 220mΩ at 10V gate drive, this device ensures efficient power handling while minimizing conduction losses. The MOSFET operates reliably up to 150°C junction temperature (TJ), making it suitable for high-temperature environments. Packaged in a TO-247 through-hole format, it provides excellent thermal dissipation, supporting a maximum power dissipation of 110W (Tc).
