The SMBJ24CA with 38.9V 26.7V 24V SMB(DO-214AA) TVS ROHS is a surface-mount transient voltage suppressor (TVS) diode manufactured by Semiware. It is designed to protect against overvoltage transients and high-energy electrical disturbances, such as electrostatic discharge (ESD), lightning, and fast transient surges. This bi-directional diode is rated for a unidirectional peak pulse power of 600W and is specially designed for applications such as data, signal, and telecom line protection, where fast response times are necessary. It also meets the requirements of RoHS (Restriction of Hazardous Substances) for maximum environmental protection.
