Zener Diode 18V 1.3W
The 18V 1.3W Zener Diode is a voltage regulation component designed to maintain a stable voltage across electronic circuits. When operated in reverse bias, the diode allows current to flow once the voltage reaches its breakdown level of approximately 18 volts, effectively clamping the voltage to protect sensitive components from over-voltage conditions. This makes it an essential component in power supply circuits, voltage reference applications, and signal protection systems.
With a power dissipation capability of 1.3 watts, this Zener diode is suitable for medium-power regulation and protection tasks. It is widely used in power supplies, microcontroller circuits, and analog electronics where consistent voltage control is required. The diode’s through-hole design ensures easy integration into PCB assemblies and prototyping environments.
