(Pack of 5) 20V 1/2 Watt 1N4747A Zener Diode

(Pack of 5) 20V 1/2 Watt 1N4747A Zener Diode 

The 20V 1/2 Watt Zener Diode is a compact and efficient voltage-regulation device designed to provide a stable 20-volt reference under reverse-bias operation. With a 0.5W (½ Watt) power dissipation rating, it is well-suited for low- to medium-power circuits. Its small axial package makes it ideal for general electronics, prototyping, and regulated voltage references in low-power applications.
