STP105N3LL Description

Short technical summary and product information.

The STP105N3LL is an N-Channel power MOSFET manufactured by STMicroelectronics. It is designed for high-efficiency power switching applications. The device features a maximum drain-to-source voltage (Vdss) of 30V and a maximum continuous drain current of 80A at Tc. The on-resistance (Rds on) is a maximum of 3.5mOhm at a gate drive of 10V and a drain current of 40A, enabling low conduction losses.

 

This MOSFET is housed in a standard TO-220-3 through-hole package, making it suitable for a wide range of power conversion and management circuits. It requires a gate drive voltage of 4.5V or 10V to achieve the specified on-resistance. The device can dissipate up to 140W of power and operates at a maximum junction temperature of 175°C. The gate charge is 42nC at 4.5V, and the input capacitance is 3100pF at 25V drain-source voltage.
