The EMZ1 Zener diode, manufactured by JSCJ (JCET), is a reliable component for voltage regulation and protection. This single diode features a power dissipation of 200mW and a Zener voltage of 5.1V. Its SOD-523 package makes it suitable for high-density surface mount assembly. Zener diodes are designed to maintain a constant voltage across their terminals when reverse biased, making them ideal for voltage stabilization, overvoltage protection, and voltage reference circuits. Supreme Components International is an authorised distributor of JSCJ (JCET) components. The EMZ1 is commonly used in power supplies, communication equipment, and consumer electronics.
