About Zener Diodes

Zener Diodes are two-terminal silicon active components designed to operate in reverse breakdown voltage regions, providing a highly stable reference voltage or voltage clamping threshold. Unlike standard diodes that burn out under reverse breakdown, Zener diodes are engineered to conduct reverse current safely once the voltage exceeds a precise threshold (Zener Voltage, VZ), making them ideal for simple voltage regulation, bias networks, and signal level clamping.

Key selection parameters include Zener voltage (VZ, ranging from 1.8V to hundreds of volts), power dissipation rating (typically 150mW to 5W), tolerance (typically 2% or 5%), dynamic impedance, temperature coefficient, and package type (surface-mount SOD-123/SOD-323, or through-hole axial). Low-current Zener diodes are highly valued in battery-powered instrumentation.
