Product details

IRFZ46NPBF — 55 V, 53 A N-Channel HEXFET in TO-220AB

The IRFZ46NPBF is an N-channel enhancement-mode MOSFET from Infineon's HEXFET series. It blocks 55 V drain-to-source and conducts 53 A continuous at 25°C case temperature, with a maximum on-resistance of 16.5 mOhm driven at 10 V gate voltage.

Active lifecycle — no obsolescence risk

The IRFZ46NPBF carries an Active product status per Infineon's latest lifecycle coding. ROHS3 compliance is confirmed, so it meets current EU and global restriction directives without exemption. For BOM planning, this part is a safe long-term selection — no need to qualify a drop-in replacement for the foreseeable future.
