IRF540N / IRF540 Mosfet Transistor (SH) TO-220 (Class-A) (White)

The IRF540N is a robust N-Channel Power MOSFET that excels at switching and amplifying electronic signals. Commonly used in DIY electronics, it is designed to handle high-current loads. Because of its low gate threshold voltage of 2-4V, it is highly compatible with microcontrollers like Arduino.

Key Specifications

• Transistor Type:N-Channel
• Package Type:TO-220AB
• Max Drain-Source Voltage :100 V
• Continuous Drain Current :Up to 33 A (at 25° C)
• Pulsed Drain Current :110 A
• Max Gate-Source Voltage: ±20 V
• On-Resistance :044 Ω (typical)

Pinout (TO-220 Package)

1. Gate (Pin 1):Controls the state of the MOSFET. Applying a positive voltage turns it ON.
2. Drain (Pin 2):The pin where the load (e.g., motor, LED) is connected.
3. Source (Pin 3):The pin connected to ground.

Common Applications

• DC Motor speed control
• LED light dimmers
• Switching power supplies
• Relay drivers
