Overview
Reviews

The 8.2V 0.5 Watt Zener Diode is a compact and dependable voltage regulation component designed to maintain a constant 8.2V in reverse bias conditions. With a power rating of 0.5 watts, this Zener diode is perfect for low-power circuits requiring over-voltage protection, voltage reference, or stable voltage regulation. Its small form factor and reliable performance make it ideal for use in DIY electronics, embedded systems, and analog circuits.

How It Works:

When reverse-biased, the 8.2V Zener Diode starts conducting once the voltage exceeds 8.2V, clamping the voltage and preventing it from rising any further. This makes it an excellent choice for protecting sensitive components from voltage spikes or for providing a reference voltage in regulated circuits. The 0.5W power dissipation rating is suitable for low-current applications, ensuring safety and stability with minimal heat generation when used properly.

Typical Use Cases:

Voltage regulation for sensor circuits or analog components
Over-voltage protection for microcontrollers and ICs
Reference voltage source in regulated power supplies
Signal clipping in communication or audio systems
Battery-powered circuit protection

Limitations:

Limited to 0.5W of power dissipation — not suitable for high-power applications
Voltage tolerance typically around ±5%, which may lead to slight variation in clamping voltage
Requires proper heat dissipation in applications near the power limit
Not ideal for circuits with high current flow
