IRF731 Description

Short technical summary and product information.

IRF731 is an N-Channel power MOSFET manufactured by Harris Semiconductor. The device is rated for a maximum drain-to-source voltage of 350 V and a continuous drain current of 5.5 A at case temperature. Maximum on-resistance is 1 Ohm at a drain current of 3 A and a gate-source voltage of 10 V.

 

Gate drive characteristics include a maximum gate-source voltage of ±20 V and a 10 V drive voltage for rated on-resistance. Total gate charge is 35 nC at Vgs = 10 V, while input capacitance is 600 pF at Vds = 25 V. Maximum power dissipation is 75 W at case temperature, with an operating junction temperature range of -55°C to +150°C.

 

The IRF731 is supplied in a TO-220-3 through-hole package (TO-220AB) and is intended for discrete power switching applications. The through-hole mounting allows straightforward board assembly and heatsinking in medium-power designs.
