STF40N65M2 Description

The STF40N65M2 from STMicroelectronics is a high-performance N-channel MOSFET designed for demanding power applications. Built using ST's advanced MDmesh™ M2 technology, it delivers an optimal balance of low on-resistance (99mΩ @ 16A, 10V) and high switching efficiency, making it ideal for high-voltage, high-current environments. With a 650V drain-to-source voltage (Vdss) and a continuous drain current (Id) of 32A (Tc), this MOSFET is engineered to handle significant power loads while maintaining thermal stability up to 150°C (TJ). Packaged in a TO220FP through-hole format, it ensures robust mechanical and thermal performance in industrial and automotive applications.

STF40N65M2 Features

• Low On-Resistance: 99mΩ @ 16A, 10V minimizes conduction losses, improving efficiency.
• High Voltage Rating: 650V Vdss ensures reliability in high-power circuits.
• Fast Switching: Gate charge (Qg) of 56.5nC @ 10V and low input capacitance (2355pF @ 100V) enhance switching speed.
• Thermal Robustness: 25W power dissipation (Tc) and a wide operating temperature range (-55°C to 150°C) suit harsh environments.
• Reliability: ROHS3 compliant, REACH unaffected, and MSL 1 (unlimited) for long-term durability.
• Drive Flexibility: Vgs(max) of ±25V and a threshold voltage (Vgs(th)) of 4V @ 250µA ensure compatibility with various gate drivers.
