IRLZ44N Datasheet. Specs and Replacement
The IRLZ44N is an N-channel logic-level MOSFET widely used in low-voltage switching applications. It features a low gate threshold voltage (VGS(th) ≈ 1-2V), allowing direct control from microcontrollers such as Arduino or Raspberry Pi. The device can handle continuous drain currents up to 47 A with low on-resistance (RDS(on) ≈ 0.022Ω), ensuring efficient power switching. Its high-speed switching capability and robust thermal characteristics make it suitable for motor drivers, LED arrays, power regulators. Proper heat sinking is recommended for high-current operations to maintain stability and prevent thermal runaway.
