SMCJ130C Application Field and Working Principle

SMCJ series of transil are ultra-small RoHS devices designed for protecting sensitive electronic components, such as components used for mobile phones, computers and ports, from overvoltage transient such as electrostatic discharge (ESD), EFT, electrical fast transients (EFT), surge, or lightning.The main features and applications of SMCJ130C Transient Voltage Suppression Diode (TVS) include:

• Surge Rating: 1500 W
• Voltage Range: 63V to 140V
• Breakdown Voltage Range: 63V to 140V
• Clamping Voltage: 80V to620V

The working principle of the TVS diode is based on the principle of a voltage control device. Voltage control devices are generally used to limit the flow of current, and the TVS diode is no exception. When the diode is subject to an overvoltage condition, the diode will conduct, which will limit the amount of voltage that can flow through the junction. This clamping voltage is the maximum voltage that will be present in the circuit, and thus the device is capable of suppressing overvoltage transients.

The SMCJ130C is designed for high-speed and reliability. It also offers ESD protection and high surge capacity, making it ideal for high-speed data applications. The device also offers a low clamping voltage and a low leakage current, making it well-suited for portable electronic applications. The device also provides high peak surge current capability, with low leakage current and low clamping voltage features ideal for digital applications.

The device also offers a wide operating temperature range. In addition to its ESD protection and high surge current capacity, the SMCJ130C also offers superior surge protection for signal line, audio line, and I/O port protection. This device is designed for one-time ESD burst protection and can withstand repetitive surges of up to 1500 W.

In summary, the SMCJ130C Transient Voltage Suppression Diode is a modern and efficient device that provides reliable protection from overvoltage transients. The device is well suited for high-speed and portable applications with high surge capability and low leakage current. It also offers a wide operating temperature range and is suitable for one-time ESD burst protection.
