STW31N65M5 Description

The STW31N65M5 from STMicroelectronics is a high-performance N-channel 650V power MOSFET designed for demanding switching applications. Built on the advanced MDmesh™ V technology, it delivers superior efficiency with low conduction and switching losses. With a continuous drain current (Id) of 22A (Tc) and a low on-resistance (Rds(on)) of 148mOhm at 10V gate drive, this MOSFET ensures high power density and thermal stability. The device operates reliably up to 150°C junction temperature (TJ) and features a robust ±25V gate-source voltage (Vgs) tolerance, making it suitable for harsh environments. Packaged in a TO-247 through-hole format, it is optimized for high-power applications requiring durability and ease of mounting.

STW31N65M5 Features

• High Voltage Rating: 650V drain-source voltage (Vdss) ensures suitability for industrial and automotive applications.
• Low Gate Charge (Qg): 45nC at 10V minimizes switching losses, improving efficiency in high-frequency circuits.
• Low Input Capacitance (Ciss): 816pF at 100V reduces drive requirements and enhances switching speed.
• Optimized Rds(on): 148mOhm at 11A, 10V for reduced conduction losses and better thermal performance.
• Robust Construction: TO-247 package with MSL1 (unlimited shelf life) ensures reliability in mass production.
• Compliance: ROHS3 and REACH compliant, meeting global environmental standards.
