IRLB8721 N Channel MOSFET 3V3 TTL Compatible

The IRLB8721 is a high-performance logic-level N-channel power MOSFET optimized for 3.3V and 5V TTL/CMOS logic control, making it the ideal choice for modern microcontroller applications including ESP32, Raspberry Pi, Arduino, and other low-voltage logic systems. This MOSFET achieves full enhancement with gate voltages as low as 3.3V, eliminating the need for gate driver circuits when switching high-current loads directly from digital outputs.

With 30V drain-source voltage rating and 62A continuous drain current capability, the IRLB8721 excels at controlling LED strips, DC motors, solenoids, heating elements, and other high-power loads. The exceptionally low on-resistance minimizes power loss and heat generation, ensuring efficient operation even at high currents. The TO-220 package allows easy heatsink mounting for demanding applications. Perfect for PWM motor speed control, LED dimming, smart home automation, and battery-powered projects where low gate voltage operation is essential for compatibility with modern 3.3V logic microcontrollers.
