Zener Diode (2V) 0.5W 5pcs

The Zener Diode (2V) 0.5W pack contains five low-voltage Zener diodes with a nominal Zener voltage of 2 V and a power rating of 0.5 W. Used in reverse bias with a series resistor, a Zener diode holds the voltage across it close to its rated value, so it can provide a simple reference voltage, clamp signals or protect sensitive low-voltage inputs.

Zener Diode (2V) 0.5W Applications

• Simple low-voltage reference
• Clamping and limiting signal voltages
• Protecting low-voltage inputs from overvoltage
• Level shifting and biasing in analog circuits
• Electronics education and diode experiments

What's in the Box

• 5 × 2 V 0.5 W Zener diodes

Tip: Connect the cathode (band) to the positive side and always use a series resistor sized so the diode power (2 V × current) stays well under 0.5 W. Low-voltage Zeners such as 2 V have a soft knee, so the voltage changes more with current than on higher-voltage types; check it with a meter in your circuit.
