STF21N65M5 Description

Short technical summary and product information.

The STF21N65M5 is an N-Channel MOSFET designed by STMicroelectronics. It features a maximum drain-to-source voltage of 650V and a continuous drain current of 17A at case temperature. The on-state resistance is typically 190mOhm maximum at 8.5A and 10V gate drive. The device has a gate charge of 50nC at 10V and input capacitance of 1950pF at 100V drain-source voltage. The maximum gate-to-source voltage is ±25V, and the gate threshold voltage is up to 5V at 250µA drain current. It is packaged in a TO-220-3 Full Pack (TO-220FP) with through-hole mounting. Maximum power dissipation is 30W at case temperature, and the junction temperature can reach up to 150°C. This MOSFET is suitable for high-voltage switching applications in power conversion and control circuits.
