HRF3205 Description

Short technical summary and product information.

The HRF3205 is an N-Channel enhancement mode power MOSFET from On Semiconductor (originally Fairchild Semiconductor). It is designed for high-efficiency switching applications.

Key electrical specifications include a 55V drain-source voltage rating, 100A continuous drain current (package limited to 75A), and 390A pulsed current capability. The device features a low on-resistance of 8 milliohms maximum at 59A and 10V gate drive. Gate charge is 170 nC at 10V, and input capacitance is 4000 pF at 25V.

Thermal characteristics include a maximum power dissipation of 175W at case temperature 25°C with a derating factor of 1.17 W/°C. The operating junction temperature range is -55°C to 175°C. The device is housed in a through-hole TO-220-3 package, suitable for PCB mounting.

Typical applications include switching regulators, DC-DC converters, motor drivers, relay drivers, and drivers for high-power bipolar switching transistors. Note that continuous current is package limited; refer to the datasheet for detailed thermal curves.
