The STMicroelectronics STF20N20 is an N-Channel MOSFET belonging to the STripFET II series, realized with STMicroelectronics' unique STripFET process. This process is specifically designed to minimize input capacitance and gate charge, making it suitable as a primary switch in advanced high-efficiency isolated DC-DC converters.
Key electrical specifications include a maximum drain-to-source voltage (Vdss) of 200V and a continuous drain current (Id) of 18A at 25°C. The on-resistance (Rds On) is a maximum of 125mOhm at 10A and 10V, with a typical value of 0.10 Ohm. The gate charge (Qg) is a maximum of 39 nC at 10V, and the input capacitance (Ciss) is a maximum of 940 pF at 25V. The maximum gate-source voltage (Vgs) is ±20V, and the gate threshold voltage (Vgs(th)) is 4V at 250µA.
This MOSFET is designed for high current switching applications and high efficiency DC-DC converters, functioning as a primary side switch. It has a maximum power dissipation of 25W (Tc) and operates within a temperature range of -55°C to 150°C (TJ).
The STF20N20 is supplied in a TO-220FP package, which is a through-hole mounting type. The product is RoHS3 compliant and has a Moisture Sensitivity Level (MSL) of 1.
