Product details

100 V, 14 mOhm — the switching-loss and conduction-loss trade-off

The IRLR3110ZTRLPBF is an Infineon HEXFET N-channel MOSFET rated for 100 V drain-source and 42 A continuous drain at 25°C case temperature. Above that, a dedicated gate driver with a 10 V rail pulls the Rds(on) down to the rated minimum.

175°C junction — where the thermal budget lands

That extra 25°C headroom matters in under-hood or sealed-enclosure designs where ambient air hits 105°C and the case-to-ambient thermal resistance is limited by the PCB copper area. Power dissipation is rated at 140 W at case temperature 25°C — the practical limit in a DPAK on a standard FR-4 board with 1 oz copper is closer to 2-3 W continuous before the junction hits 175°C.

DPAK footprint and supply-chain fit

No re-spin needed if you have a DPAK land pattern on the board. ROHS3 compliant.

Frequently asked questions

Where can I buy IRLR3110ZTRLPBF available via RFQ confirmation?

Submit a request with your target quantity and we will quote against it.

Can I use IRLR3110ZTRLPBF in a 12V system?

Yes. The 100 V drain-source rating gives 8× margin on a 12 V bus, and the 4.5 V gate-drive threshold means a 5 V or 3.3 V logic signal can turn it on fully. The 14 mOhm Rds(on) at 10 V gate drive drops to roughly 18-20 mOhm at 4.5 V — still low enough for a 10 A load in a 12 V system to stay under 2 W conduction loss.

What is the difference between IRLR3110ZTRLPBF and IRLR3110ZTRPBF?

The suffix difference is packaging: TRPBF is typically Tape & Reel with a different reel quantity or tape width compared to TRLPBF. The electrical specifications — 100 V Vdss, 42 A Id, 14 mOhm Rds(on), 48 nC gate charge — are identical. Confirm the reel quantity and tape dimensions with your distributor before ordering if your feeder setup is specific.
