Product details

8 mOhm at 10 V — where the conduction loss lands

The IRFI3205PBF: The full-pack TO-220 isolates the tab electrically, so no insulating pad is needed — useful when multiple devices share a heatsink.

Gate charge and switching speed — what 170 nC means for the driver

Total gate charge is 170 nC at 10 V. The 4000 pF input capacitance at 25 V drain-source gives a figure for estimating turn-on delay and Miller plateau duration in a hard-switched topology.

Temperature range — military-grade junction span

The 175 °C Tj(max) also provides headroom for transient overloads in motor-drive or DC-DC converter applications.

Frequently asked questions

Can IRFI3205PBF be used for motor control applications?

Yes. The 55 V drain-source rating and 64 A continuous current handle typical 24 V or 48 V brushless DC motor drives. The 8 mOhm Rds(on) keeps conduction losses low, and the 170 nC gate charge is manageable with a standard gate driver at PWM frequencies up to 50 kHz.
