STD8N65M5

STD8N65M5 Description

The STD8N65M5 from STMicroelectronics is a high-performance N-channel MOSFET designed for demanding power management applications. With a 650V drain-to-source voltage (Vdss) and 7A continuous drain current (Id), it delivers robust performance in high-voltage circuits. Part of the MDmesh™ V series, it leverages advanced Metal Oxide Semiconductor (MOSFET) technology to achieve low conduction losses and high switching efficiency. Packaged in a DPAK (TO-252) surface-mount format, it is optimized for space-constrained designs while ensuring reliable thermal dissipation up to 150°C junction temperature (TJ).

STD8N65M5 Features

• Low On-Resistance: 600mΩ (max) @ 3.5A, 10V (Rds On), minimizing power losses.
• Fast Switching: Gate charge (Qg) of 15nC @ 10V and input capacitance (Ciss) of 690pF @ 100V ensure efficient high-frequency operation.
• High Voltage Tolerance: 650V Vdss with ±25V gate-source voltage (Vgs) capability for rugged applications.
• Thermal Efficiency: 70W power dissipation (Tc) and DPAK package enhance heat management.
• Reliability: ROHS3 compliant, REACH unaffected, and MSL 1 (unlimited) for environmental and handling robustness.
• Optimized Drive: 10V drive voltage for full enhancement, reducing switching losses.
