N-Cha MOSFET Transistors FQP50N06
N-Channel MOSFET Transistor – FQP50N06
Overview:
The FQP50N06 is a robust N-Channel enhancement-mode MOSFET capable of handling high current and voltage with fast switching capabilities. It's ideal for power switching, motor control, LED dimming, and relay driving in Arduino, Raspberry Pi, and other microcontroller projects. Its TO-220 package allows easy mounting with heatsinks for thermal management.
Key Features:
High-current capacity up to 52A continuous drain current
Low on-resistance: efficient power switching
Logic-level gate drive compatible (can be controlled directly by 5V logic)
Maximum drain-source voltage of 60V
TO-220 package for easy installation and heat dissipation
Fast switching and low gate charge for PWM applications

| GND | Source |
| Load → +V | Drain |
💡 Use a 220Ω resistor between Arduino pin and Gate. Add a flyback diode across inductive loads like motors or relays.
Sample Code (Arduino):
CopyEditint mosfetPin = 6; // Connected to Gate void setup() { pinMode(mosfetPin, OUTPUT); } void loop() { digitalWrite(mosfetPin, HIGH); // Turn ON load delay(1000); digitalWrite(mosfetPin, LOW); // Turn OFF load delay(1000); }
Applications:
Motor and solenoid control
LED strip or high-power lighting dimming
Relay and power supply switching
Battery-powered devices
PWM-based control systems
