The BZT52C18-A Zener diode, manufactured by SMC DIODES, is a crucial component for voltage regulation and circuit protection. Supreme Components International is an authorised distributor of SMC DIODES, ensuring you receive genuine and high-quality parts. This diode features a Zener voltage of 18V and a power dissipation of 500mW, making it suitable for a wide range of applications. Encased in a small SOD-323 package, it's ideal for space-constrained designs. Zener diodes are designed to maintain a constant voltage across their terminals when reverse biased, providing a stable voltage reference or protecting sensitive circuits from voltage spikes. The BZT52C18-A is commonly used in voltage regulators, overvoltage protection circuits, and clipping circuits. Its robust design and reliable performance make it a valuable asset in any electronic project.
