The CMPZDA18V Zener diode, manufactured by CENTRAL SEMICONDUCTOR, is a crucial component for voltage regulation and protection circuits. Supreme Components International is an authorised distributor of CENTRAL SEMICONDUCTOR components, ensuring you receive genuine and high-quality products. This diode, housed in a compact SOT-23 package, offers an 18V Zener voltage and a power dissipation of 0.225W. Its small size makes it suitable for space-constrained applications. Zener diodes are designed to maintain a constant voltage across their terminals when reverse biased, making them ideal for voltage stabilization, voltage referencing, and overvoltage protection. The CMPZDA18V is commonly used in power supplies, communication equipment, and instrumentation.
