The Yageo SJD12C28L01 is a Thyristor Surge Suppressor Diode chip, packaged in a SOD-123S case and compliant with RoHS standards. It offers exceptional Transient Voltage Suppression (TVS) protection through its rapid clamping response and is suitable for use in any type of circuit requiring overvoltage protection. It has an operating voltage range of 12V and a breakdown voltage of 28V, making it suitable for use in many applications. It is designed to protect against Electrostatic Discharge (ESD) due to its specific ESD clamping characteristics. Additionally, this diode is highly reliable with an operating junction temperature range of -55°C to +150°C.
