Product details

200 V N-channel HEXFET in a fully isolated TO-220

Its key feature is the TO-220 Full-Pak (fully isolated tab) package, which eliminates the need for an insulating washer between the device and heatsink — a timesaver in through-hole power layouts. Typical applications include DC-DC converters, motor drives, power supplies, and battery management circuits where 200 V blocking and moderate current are required, across industrial and telecom environments.

110 nC gate charge — sizing the gate driver

Gate charge is 110 nC at 10 V. Input capacitance is 4600 pF at 25 V.

Full-Pak package — no isolator needed

The TO-220 Full-Pak (also called TO-220AB Full-Pak) moulds the plastic body around the entire tab, so the mounting surface is electrically isolated from the drain. This means the device can be bolted directly to a grounded heatsink or chassis without an insulating pad and washer. The through-hole mounting is standard for point-to-point wiring or PCB mounting where a single screw holds the device.

The IRFI4227PBF has Active product status and ROHS3 compliance.

Frequently asked questions

What is the Rds(on) of IRFI4227PBF?

The maximum on-resistance is 25 mOhm at 17 A drain current with a 10 V gate drive.

Can IRFI4227PBF replace IRFI4227?

The IRFI4227PBF is the lead-free (PbF) version of the IRFI4227. The electrical specifications — 200 V Vdss, 26 A Id, 25 mOhm Rds(on) — are identical. The PBF suffix indicates RoHS3 compliance. In most designs it is a drop-in replacement, but verify the date code and any subtle package marking differences if the original IRFI4227 was used in a qualified assembly.
