Product details

100 V N-channel in a DirectFET can

The IRF6644TRPBF: The 13 mOhm max Rds(on) at 10 V gate drive sets the conduction loss floor — at 10.3 A the dissipation is under 1.4 W, which the DirectFET Isometric MN package can sink to the board without a separate heatsink in many layouts.

Gate charge and switching budget

Total gate charge Qg is 47 nC at 10 V. Driving this at 100 kHz requires an average gate current of about 4.7 mA from the driver — well within the capability of a standard gate-drive IC. The 2210 pF input capacitance at 25 V drain-source gives a rough Ciss figure for estimating switching losses in a hard-switched converter.

Frequently asked questions

Can IRF6644TRPBF be used for 24V systems?

Yes, the 100 V drain-source rating provides ample headroom for 24 V bus rails — the derating margin is over 4×, which keeps the device well within its safe operating area even under transient overvoltage conditions.
