IRFR3711ZTRPBF

IRFR3711ZTRPBF is an N-channel enhancement-mode power MOSFET from IR/Infineon. It’s intended for low-voltage, high-current switching applications such as DC-DC converters, motor drivers, and load switches. The device offers a 30 V (typical) drain‑source rating with a very low on-resistance (Rds(on) in the milliohm range), enabling low conduction losses at high currents. Gate drive can be at common logic‑level voltages (Rds(on) specified at Vgs=4.5 V and 10 V), making it compatible with microcontroller or gate-driver outputs. It features fast switching, good ruggedness for switching applications, and Pb-free RoHS-compliant packaging (suffix PBF in a ZTR package). Typical uses include synchronous buck converters, switching regulators, and automotive electronics. For exact Vds, Id, Rds(on), and pinout, refer to the official datasheet.

IRFR3711ZTRPBF features (concise):
- N-channel enhancement-mode power MOSFET
