The ZJ4.7A Zener diode, manufactured by FORMOSA MICROSEMI, is a crucial component for voltage regulation and circuit protection. This diode features a Zener voltage of 4.7V and a power dissipation of 500mW. Encased in a DO-41 package, it's suitable for through-hole mounting on PCBs. Zener diodes are designed to maintain a constant voltage across their terminals when reverse biased, making them ideal for creating stable voltage references and protecting sensitive circuits from overvoltage conditions. Supreme Components International is an authorised distributor of FORMOSA MICROSEMI components, ensuring you receive genuine and high-quality products. This Zener diode is commonly used in power supplies, voltage regulators, and surge protection circuits.
