# IRLZ44ZPBF (Component)

## Description

N\-Channel Logic\-Level Power MOSFET – The Infineon IRLZ44ZPBF is a power switching transistor designed for DC\-DC converters, motor control, battery management, and power switching applications\. It features a 55 V drain\-to\-source voltage, 51 A continuous drain current \(at \\\(T\_C=25^\\circ\\text\{C\}\\\)\), 13\.5 mΩ maximum on\-resistance at \\\(V\_\{GS\}=10\\text\{ V\}\\\), and ±16 V maximum gate\-to\-source voltage\. It supports 4\.5 V gate drive and is housed in a TO\-220AB through\-hole package, with an operating junction temperature range of −55°C to \+175°C\.
