Diodes for Arduino, ESP32 & Electronics Projects

Diodes are commonly used with Arduino compatible boards, ESP32, ESP8266, Raspberry Pi compatible boards, relay modules, motors, power supplies, LEDs, sensors, transistors, MOSFETs and general electronic components. They can control current direction, protect circuits, clamp voltage spikes and support rectification circuits.

Always check diode type, voltage rating, current rating, forward voltage drop, recovery speed, package type and circuit requirements before ordering. Using the wrong diode can cause overheating, voltage drop issues or circuit failure.

Rectifier Diodes, Schottky Diodes, Zener Diodes & Bridge Rectifiers

Different diodes suit different applications. Rectifier diodes are commonly used in power circuits. Schottky diodes are useful where low forward voltage is important. Zener diodes are commonly used for voltage reference or limiting circuits. Bridge rectifiers are used when converting AC into DC.

Frequently Asked Questions

What are diodes used for?

Diodes are used to allow current to flow in one direction, protect circuits, rectify AC into DC, clamp voltage spikes and support many power and signal circuits.

What is a rectifier diode used for?

A rectifier diode is commonly used in power supply circuits to convert AC into DC or to control current flow in power circuits.

What is the difference between a Schottky diode and a standard diode?

A Schottky diode usually has a lower forward voltage drop and faster switching behaviour than many standard diodes, making it useful in some power and switching circuits.

What is a Zener diode used for?

A Zener diode is commonly used for voltage reference, voltage limiting and basic protection circuits when used correctly.

Can you help me choose the right diode?

Yes. If you are unsure which diode suits your circuit, contact AuscomTech with your voltage, current, circuit purpose, existing part number and any photos or markings from the component.
