The IRFR3710ZTRPBF: Total gate charge is 100 nC at 10 V. Input capacitance is 2930 pF at 25 V.
Junction temperature range is -55 to 175 °C — the 175 °C ceiling suits high-ambient environments like motor drives or under-hood automotive.
ROHS3 compliant, so no exemption paperwork for EU/UK markets.
The IRFR3710ZTRPBF is the tape-and-reel, RoHS-compliant version of the IRFR3710Z. Electrical ratings — 100 V Vdss, 42 A Id, 18 mOhm Rds(on) — are identical. The suffix 'TRPBF' indicates Tape & Reel packaging and lead-free plating. It is a drop-in replacement for the IRFR3710Z in the same DPak footprint, provided the board is compatible with lead-free solder profiles.
That is the worst-case figure at 25 °C junction; actual on-resistance will be lower at lower current and will increase with junction temperature — expect roughly 1.5× the 25 °C value at 125 °C junction.
Yes, the TRPBF suffix designates Tape & Reel packaging. It is also available as Cut Tape (CT) for smaller quantities. The DPak (TO-252) body is compatible with standard SMT pick-and-place.
Yes, it is ROHS3 compliant — no exemptions for lead, mercury, cadmium, or the other restricted substances. The 'PBF' in the order code indicates lead-free (Pb-free) plating.
