Transistors & MOSFETs for Arduino, ESP32 & Electronics Projects
Transistors and MOSFETs are commonly used with Arduino compatible boards, ESP32, ESP8266, Raspberry Pi compatible boards, LEDs, motors, relays, buzzers, solenoids, sensors and power circuits. They allow a small control signal to switch or control a larger current when used correctly.
Always check transistor type, MOSFET channel type, voltage rating, current rating, power dissipation, package type, pinout, gain, gate threshold voltage and whether the device is suitable for your circuit before ordering.
NPN Transistors, PNP Transistors, N-Channel MOSFETs & Logic Level MOSFETs
NPN and PNP transistors are commonly used for small-signal switching and amplification. MOSFETs are often used where higher-current electronic switching or lower power loss is required. Logic level MOSFETs are especially useful in microcontroller projects because they can be driven from lower logic voltages when selected correctly.

Frequently Asked Questions
What are transistors used for?
Transistors are used for switching, amplification, signal control and driving small loads in electronic circuits.
What are MOSFETs used for?
MOSFETs are commonly used for electronic switching and power control, especially for DC loads such as LEDs, motors, solenoids and other low-voltage devices when used correctly.
What is the difference between a transistor and a MOSFET?
A bipolar transistor is current-controlled and commonly used for small-signal switching or amplification. A MOSFET is voltage-controlled and often used for efficient electronic switching and power control.
What is a logic level MOSFET?
A logic level MOSFET is designed to turn on at lower gate voltages, making it suitable for some microcontroller projects. Always check the datasheet and current requirements before use.
