Product details

Conduction and switching parametrics

With a total gate charge of 55 nC at 10 V and an input capacitance of 3100 pF at 10 V drain-source, the STP140N6F7 presents a moderate gate-drive load — suitable for standard gate-driver ICs in hard-switched topologies up to several tens of kilohertz. Maximum power dissipation is 158 W at the case temperature, and the junction temperature rating of 175 °C allows operation in thermally demanding environments such as motor drives and power supplies.

Package and mounting for the BOM

The through-hole mounting suits wave-solder assembly and field replacement in industrial equipment.

Frequently asked questions

Can STP140N6F7 replace IRFZ44N?

Both are 60 V N-channel MOSFETs in TO-220 packages, but the STP140N6F7 offers a lower 3.5 mOhm Rds(on) versus the IRFZ44N's typical 17.5 mOhm, and a higher 80 A continuous drain rating. Pin-compatibility should be verified against the specific gate-drive voltage and switching frequency of your circuit.
