(Pack of 5) 4.7V 1/2W Zener Diode

(Pack of 5) 4.7V 1/2W Zener Diode 

This pack includes five 4.7V Zener diodes rated at 0.5W (½ watt). These diodes provide a stable 4.7V reference voltage when reverse-biased in the Zener breakdown region. They are ideal for low-power voltage regulation, signal clamping, and protection circuits in compact electronic designs. Typically supplied in a DO-35 axial package, they are easy to use in breadboards, hobby circuits, and PCB assemblies.
