The SMC30J22CA is a robust transient voltage suppressor (TVS) diode designed by STMicroelectronics, a global semiconductor leader. This TVS diode is specifically engineered to protect sensitive electronic equipment from voltage transients induced by system inductive load switching and lightning strikes. With its high surge capability, it is an ideal solution for safeguarding high-speed communication lines, VCC bus, and other vulnerable circuits.

Key Features

• Stand-off Voltage: The device has a stand-off voltage of 22V, which ensures that it remains non-conductive under normal operating conditions, preventing unnecessary power consumption.
• Peak Pulse Power: It can handle peak pulse power dissipation of 3000W at 10/1000μs waveform, which is critical for absorbing high-energy spikes and protecting the downstream components.
• Clamping Voltage: Upon encountering a voltage spike, the SMC30J22CA clamps to a low maximum of 35.5V, thereby shielding connected components from potential damage.
• Bi-directional Protection: The bi-directional configuration provides symmetrical protection for both polarities of voltage transients, making it suitable for AC applications or bipolar signal lines.
• Low Leakage Current: Its low leakage current ensures minimal power loss when the device is in standby mode, enhancing the overall efficiency of the application.
• Package: Housed in a compact SMC package, the device offers a space-saving solution without compromising on performance.
• Compliance: It complies with industrial standards such as IEC 61000-4-2 and IEC 61000-4-5, ensuring reliability in harsh environments.
