IRLZ44 N Channel MOSFET 5V TTL Compatible

The IRLZ44N is a logic-level N-channel power MOSFET specifically designed for 5V TTL/CMOS logic control, making it perfect for Arduino, Raspberry Pi, and microcontroller switching applications. Unlike standard MOSFETs requiring 10V gate drive, the IRLZ44N achieves full enhancement with just 5V gate voltage, allowing direct control from digital outputs without additional driver circuits. This makes it ideal for switching high-current loads such as LED strips, motors, solenoids, and heating elements.

With 55V drain-source voltage rating and 47A continuous drain current capability, this MOSFET handles demanding power switching applications with low on-resistance for minimal heat generation. The TO-220 package provides excellent thermal performance and easy heatsink mounting for high-power applications. Popular in PWM motor control, LED dimming circuits, relay replacement, and automated switching systems. The low gate threshold voltage ensures reliable switching even with 3.3V logic systems, offering versatility across various microcontroller platforms.
