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 DPAK (TO-252) surface-mount package has the tab as the drain connection — the PCB copper area under the tab sets the thermal resistance to ambient, so the layout must allocate enough copper pour for the expected dissipation. 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.
