Product details

17 mOhm at 9 A — the conduction-loss floor for a 40 V FET

The 17 mOhm maximum on-resistance at Vgs=10 V sets the conduction loss in a buck converter or load switch — at 5 A the I²R loss is under 0.5 W, which keeps the junction temperature within the -55°C to 150°C operating range even in a still-air 8-SOIC layout.

Gate drive at 4.5 V — no separate driver needed

The 23 nC total gate charge at 4.5 V means a 5 V PWM output from a microcontroller or a 3.3 V logic signal level-shifted to 5 V can switch this FET at moderate frequencies (tens of kHz) without a dedicated gate-driver IC. The ±20 V Vgs(max) gives headroom for gate ringing on long PCB traces.

It is ROHS3 compliant.

Frequently asked questions

Is IRF7469TRPBF compatible with 5 V gate drive?

Yes. The Rds(on) at 4.5 V is not specified separately, but the typical curve in the datasheet shows it rises to about 1.5× the 10 V value — still under 30 mOhm for most load conditions.

Is IRF7469TRPBF an equivalent to IRF7469PBF?

The IRF7469PBF is the lead-free, non-tape-and-reel variant of the same die. The TRPBF suffix indicates Tape & Reel packaging. Electrically they are identical — same 40 V Vdss, 9 A Id, 17 mOhm Rds(on), and same 8-SO package. The PBF suffix confirms lead-free (ROHS) compliance on both.
