INFINEONIRLZ 44N

IRLZ44N N-Channel Logic Level Power MOSFET 55V 47A TO-220 by International Rectifier / Infineon, suitable for power switching circuits, DC loads, PWM control, LED drivers and motor control applications.

The IRLZ44N is an N-Channel Power MOSFET using HEXFET / IR MOSFET technology, originally from International Rectifier and now from Infineon. It features 55V Drain-Source voltage, continuous Drain current up to 47A and low RDS(on) of 22mOhm max at VGS 10V. As a logic-level MOSFET, it can be driven more effectively from lower gate voltages compared with standard MOSFETs such as the IRFZ44N, with RDS(on) of 35mOhm max at 4.5V.

Technical description

The IRLZ44N is suitable for use as a power switch in low-voltage DC applications. The TO-220 package allows easy PCB mounting and heatsink use when load current or thermal dissipation requires it. The logic-level gate makes it useful in Arduino, microcontroller and PWM drive circuits, provided that current, temperature and heat dissipation limits are respected.

Typical applications

Suitable for DC motor control, LED dimmers, PWM switching, load switches, battery powered circuits, robotics projects, power supplies, small power converters, automation systems, electronic projects and general DC load switching applications.

Compatibility note

The IRLZ44N is a logic-level MOSFET and is more suitable than the IRFZ44N for 5V logic drive. For 3.3V drive or high current operation, conduction losses, temperature and actual VGS must be checked. In power applications, proper heatsinking and correct gate drive design are recommended.
