Zener Diodes
Looking for high-performance zener diodes for your electronics projects? Vetco Electronics offers one of the most diverse and dependable selections of zener diodes in the market, whether you’re prototyping a circuit, replacing components, or designing voltage regulation systems for commercial applications.
What is a Zener Diode?
A zener diode is a special type of diode designed to allow current to flow not only from its anode to its cathode (like a regular diode) but also in the reverse direction when the voltage exceeds a specific threshold known as the Zener breakdown voltage. This makes zener diodes ideal for voltage regulation, surge protection, and reference voltage generation in low and high-voltage circuits.
At Vetco, we carry a wide selection of voltage ratings, including 3.3V zener diode, 5V zener diode, 5.1V, 12V, 15V, 18V, 20V, 24V, and even high-voltage options like 100V zener diodes.
Why Use Zener Diodes?
Zener diodes are commonly used for:
- Maintaining stable voltage in power supply circuits
- Over-voltage protection in sensitive electronics
- Signal clipping in audio and RF circuits
- Voltage references for analog-to-digital converters (ADCs)
For compact or high-efficiency builds, we also offer high-power zener diodes and double zener diodes for specialized configurations.
Shop by Voltage, Model, and Package
Vetco’s inventory includes axial and surface-mount zener diodes across multiple power ratings and breakdown voltages. Whether you need a 5.6V zener diode for a logic circuit or a 120V zener diode for a high-voltage application, our catalog is easy to browse and supported by our expert customer service.
