Product details

Gate charge and drive voltage

Total gate charge is 35 nC at 5 V. That keeps the drive current modest — a 1 A gate driver can switch it at 100 kHz with under 3.5 mA average draw.

175 °C junction — high-temp environments

That qualifies it for under-hood automotive or industrial enclosures where ambient can push 125°C — the 175°C ceiling leaves thermal margin for self-heating.

Active production, DPAK footprint

The DPAK tab is the thermal pad; the board layout should connect it to a copper plane for the full 110 W power dissipation. ROHS3 compliant per the listing.

Frequently asked questions

Can I use IRLR2905ZTRPBF instead of IRLR2905?

The IRLR2905ZTRPBF is the Tape & Reel variant of the base IRLR2905. The die and ratings are identical — 55 V, 42 A, 13.5 mOhm Rds(on). The only difference is the packaging medium: TR vs tube or bulk. If your pick-and-place feeder accepts Tape & Reel, it is a direct substitute.
