Product details

Junction temperature and switching budget

The 37 nC total gate charge at 10 V means a 1 A gate driver can switch this FET at roughly 27 kHz before the average gate-drive current hits 1 A — a practical ceiling for hard-switched topologies. That capacitance, combined with the gate-drive source impedance, sets the turn-on and turn-off delay; a 10 Ω gate resistor and a 1 A driver yields a ~10 ns rise time, which keeps switching losses manageable up to 100 kHz in a clamped-inductive load.

Through-hole TO-220AB — heatsink-ready

The TO-220AB package (TO-220-3) is a through-hole, single-gauge tab with a mounting hole for a screw-on heatsink.

Frequently asked questions

What is the Vdss of IRF530NPBF?

The drain-to-source voltage rating is 100 V. That is the maximum voltage the FET can block when off; for reliable operation, derate to 80 V or less in continuous switching applications.

Can I use IRF530NPBF for PWM applications?

Yes. The 37 nC gate charge and 920 pF input capacitance are moderate — a 1 A gate driver can switch this FET at tens of kHz with acceptable gate-drive losses. For frequencies above 100 kHz, the switching losses in a hard-switched topology may dominate the thermal budget; a lower-Qg part would be a better fit.
