The BZT52C18S-TP with Zener Diodes 200mW 18V manufactured by Micro Commercial Components (MCC) is a single diode with a 200mW 18V zener voltage rating. It is housed in a compact SOT-23 package and can handle currents up to 500mW. The device includes an integrated surge current protection that helps protect against spikes in voltage. It also has a unique Zener reverse-bias voltage breakdown characteristic, which helps suppress transient-voltage spikes across a variety of applications. It has a low zener impedance, which helps keep the device operational with minimal power dissipation. It is suitable for use in a variety of applications, such as voltage regulation, voltage clamping, and overvoltage protection.
