General-Purpose TVS Diode

SMBJ30CAActive

SMBJ30CA is a bidirectional TVS diode in SMB package. Its main function is to quickly conduct and clamp the overvoltage within a safe range when the circuit is impacted by transient overvoltage (such as ESD, lightning strike, inductive load switching, etc.), thereby effectively protecting downstream sensitive electronic components from damage. Its bidirectional symmetrical structure is suitable for AC or bipolar signal environments, and its 30V operating voltage range makes it widely used in 24V power supply systems, communication interfaces, power control lines and other occasions that require anti-interference protection. When encountering a surge, the device can respond within nanoseconds and provide stable and reliable overvoltage protection. It is a common protection component in industrial, communication and automotive electronic systems.
