Tutorial: How to Use the MOSFET Transistor BS170

The MOSFET transistor BS170 is a fundamental component for anyone who wants to control higher current loads with small logic signals. Ideal for Arduino and Raspberry Pi projects.

What you need

• Arduino Uno
• USB power supply
• Dupont connectors

Steps

1. Connect the BS170 GATE pin to the DIGITAL pin of an Arduino output.
2. Connect the BS170 DRAIN and SOURCE pins to the two ends of the load you want to control.
3. Check the component polarity (DS is from left to right).
4. Write an Arduino sketch to send a HIGH or LOW signal to the GATE of the MOSFET.
5. Test the circuit with an LED bulb as a test load.

Example code

void setup() {
pinMode(9, OUTPUT);
digitalWrite(9, HIGH);
}

void loop() {}

Mini project

Create a switch to control an LED bulb with Arduino and BS170.

Common mistakes

• Connect the GATE to the DRAIN or SOURCE
• Do not check the polarity of the MOSFET
• Use a load that is too high
• Ignore the maximum current specifications

Recommended accessories

• Arduino Uno R3
• LED bulb
• LED resistor
• USB power supply

Frequently asked questions

What is the gate-source voltage Vgs of the BS170?
Check the datasheet.

Which pin of the Arduino should I use?
You can use any DIGITAL pin, for example pin 9.

Can I control a motor with the BS170?
Yes, but make sure to have a heat sink if the current is high.
