STMicroelectronics STP105N3LL is an N-Channel Power MOSFET from the DeepGATE™, STripFET™ VI series. This component offers a 30V drain-source voltage and a continuous drain current of 80A at 25°C, with a maximum power dissipation of 140W (Tc). Featuring a low on-resistance of 3.5mOhm at 40A and 10V, this MOSFET is designed for efficient power switching applications. Its gate charge is 42nC at 4.5V, and input capacitance is 3100pF at 25V. The STP105N3LL is housed in a TO-220-3 through-hole package, suitable for mounting in various electronic systems. It operates effectively within a temperature range of 175°C (TJ) and supports gate-source voltages up to ±20V, with a threshold voltage of 2.5V at 250µA. This device finds application in power management, automotive systems, and industrial power supplies.
