IRF643 Description

Short technical summary and product information.

The IRF643 is an N-Channel enhancement-mode power MOSFET designed for high-efficiency switching applications. It offers a drain-source voltage of 150V and continuous drain current of 16A at 25°C case temperature. The device features a maximum on-resistance of 220mOhm at 10V gate drive and 10A drain current. Gate threshold voltage is 4V maximum at 250µA. Total gate charge is 64nC at 10V, and input capacitance is 1275pF at 25V drain-source. The MOSFET is housed in a TO-220-3 through-hole package (TO-220AB), suitable for power dissipation up to 125W at 25°C case temperature. Operating junction temperature range is -55°C to 150°C. This device is suitable for switching power supplies, motor control, and other power management circuits.
