.The BZT52C27S with Zener Diodes SOD-323 RoHS is a two-terminal, surface mount diode manufactured by High Diode. It is housed in a SOD-323 package and is RoHS compliant, making it an environmentally friendly choice. The diode has a Zener Breakdown Voltage of 27 volts, and can be used to regulate voltage by allowing current to flow in one direction but blocking current in the reverse direction. The BZT52C27S has a low leakage current rating that ensures reliable performance and long lifespan. It is especially suited for applications that require low power and high reliability, such as consumer electronics, automotive electronics, and portable devices.
