The STF21N90K5 is an N-Channel power MOSFET manufactured by STMicroelectronics. It is rated for a maximum drain-to-source voltage (Vdss) of 900V and a continuous drain current (Id) of 18.5A at case temperature (Tc). The device features a low on-resistance (Rds(on)) of 0.25 ohms max at 9A, 10V gate drive, making it suitable for high-efficiency switching applications.
The gate charge (Qg) is 43 nC max at 10V, and the input capacitance (Ciss) is 1645 pF max at 100V. The maximum gate-source voltage is ±30V, and the threshold voltage is 5V max at 100µA. The device can dissipate up to 40W of power (at Tc) and operates over a junction temperature range of -55°C to +150°C.
The MOSFET is packaged in a TO-220 Full Pack (TO-220FP) which provides electrical isolation and improved thermal performance. It is designed for applications such as switching power supplies, motor control, and high-voltage DC-DC converters.
