The BZT52C8V2S is an 8.2V~8.7V 200mW 8.2V Zener Diode (also known as a voltage regulator diode) made by Yongyutai Electronics. It has a low noise voltage regulation for improved performance, and the low-profile SOD-323 (also known as SC-70) package allows for easy mounting on a board. The BZT52C8V2S is RoHS compliant, and as it is an ultra-small body package, it is very lightweight with a high power density and low power consumption. It is used to regulate the voltage in applications such as communications and test instrumentation circuit, switching power supplies, mobile phones, recorders, and general purpose circuit protection.
