TVS - Diodes - SMCJ40CA-13 application field and working principle
Currently, with the rapid development of electronics industry, static electricity, lightning, equipment switching and high frequency noise have become the focus of attention for electronic device manufacturers. The TVS diode is a kind of electrical protection device which is often used to protect electronic equipment from the above factors. It requires a certain working voltage and power, as well as a certain performance, to effectively protect electronic equipment. The SMCJ40CA-13 is a high-performance low-capacitance unidirectional TVS diode from STMicroelectronics. This diode is housed in a 3.4mm x 3.1mm surface-mount package and is designed to protect sensitive, low voltage electronic components. It is capable of protecting components from signals with maximum peak pulse power of up to 140W, while maintaining a low capacitance level of 2.2pF.As an electronic protection device, the working principle of SMCJ40CA-13 is based on clamping technology. It is used to clamp or direct the overvoltage, making the required overvoltage dissipated in the device. By doing this, it can effectively protect the equipment. When the power surge exceeds the rated reverse voltage, the diode will enter the breakdown state, and the overvoltage will pass through the diode.The application field of SMCJ40CA-13 is mostly directed at devices using I/Os in IEC-61000-4-2 surge protection for Ethernet, wireless LAN and other communication interface applications. It is suitable for USB2.0(with ESD), USB3.0, HDMI, SATA, FCC compliant Computer port, network protection, automotive (CAN Bus) as well as USB 2.0 and USB 3.0 power port applications.The main performance parameters of the SMCJ40CA-13 include a maximum repetitive peak pulse reverse voltage of up to 40V, maximum peak pulse power of up to 140W, and a low capacitance level of only 2.2pF. In addition, this diode supports a rated peak pulse current of up to 150A, surge clamp voltage of up to 27.3V and reverse surge current of up to 1.4A. Moreover, the operating temperature range is -55°C to 125°C.In conclusion, for any device that is vulnerable to overvoltage, the SMCJ40CA-13 will be an ideal choice. Featuring low-capacitance and high-performance protection, it can eliminate the damage of electrostatic discharge embers and also provide reliable overvoltage protection.The specific data is subject to PDF, and the above content is for reference
