Product details

100 V, 8.7 A N-channel HEXFET — the BOM-fit ceiling

Gate charge totals 10 nC at 10 V, so a 1 A gate driver can switch the FET in roughly 10 ns — this low Qg makes the part suitable for medium-frequency SMPS, DC-DC converters, and motor-drive output stages where switching losses matter.

DPak (TO-252) footprint — thermal and layout notes

The 310 pF input capacitance at 25 V drain-source means the gate driver sees a moderate capacitive load — a 10 Ω series gate resistor keeps the ringing under control without slowing the edge too much.

Frequently asked questions

What is the difference between IRFR120ZTRPBF and IRFR120Z?

The IRFR120ZTRPBF is the tape-and-reel packaged variant of the IRFR120Z die in the DPAK case. The suffix 'TRPBF' indicates Tape & Reel delivery and ROHS3 compliance. The die and electrical ratings are identical to the tube-shipped IRFR120Z.
