The SMBJ13A TVS diode, manufactured by Ruilongyuan, is an SMB (DO-214AA) RoHS compliant component. It is a bidirectional device, meaning that it is able to protect sensitive components from both transient induced over-voltages, such as Electrostatic Discharge (ESD) events, as well as overvoltage conditions. It features a breakdown voltage of 13 V and a maximum peak pulse power of 600 W (10/1000 µs pulse), making it ideal for protection in applications like automotive, industrial, and medical electronics. The device is packaged in SMB, allowing for easy integration into surface mount circuits while providing excellent thermal resistivity for enhanced reliability.
