STF2N80K5 Description

Short technical summary and product information.

The STF2N80K5 is an N-Channel power MOSFET from STMicroelectronics, designed for high-voltage switching applications. It features a maximum drain-to-source voltage (Vdss) of 800V and a continuous drain current of 2A (at Tc). The device offers a low on-resistance of 4.5 Ohm maximum (tested at 1A, 10V), ensuring efficient power handling.

With a gate charge of just 3 nC (max at 10V) and an input capacitance of 95 pF (max at 100V), the STF2N80K5 provides fast switching performance. The maximum gate threshold voltage is 5V at 100µA, and the maximum gate-source voltage is 30V. The device can dissipate up to 20W (at Tc) and operates over a wide junction temperature range from -55°C to 150°C.

The MOSFET is packaged in a TO-220-3 Full Pack (TO-220FP) through-hole package, which offers good thermal performance and ease of mounting on a heatsink. The part is RoHS3 compliant (unverified) and rated with MSL 1 unlimited.
