IRLZ34N N-Channel MOSFET – 55V, 30A, Logic Level TO-220 Power Transistor

📝 Product Description

The IRLZ34N is a logic-level N-Channel MOSFET designed for high-efficiency switching and amplification in low-voltage circuits. With a drain current of 30A, low RDS(on) of 35mΩ, and logic-level gate drive capability, it can be controlled directly from microcontrollers (like Arduino, STM32, ESP32) and IC outputs without needing additional driver circuits.

Packaged in a TO-220AB case, the IRLZ34N is widely used in DC motor control, LED dimming, power supplies, inverters, and battery management systems. Its high pulsed current rating (up to 110A) and rugged design make it suitable for demanding applications.
