Transient voltage suppressors, better known in the industry as TVS diodes, form an integral part of electrical circuits to help prevent surges and voltage spikes. These devices continue to prove indispensable in an array of applications due to their reliability, low cost, wide assortment of packages, and power dissipation capabilities. The SMCG130A-E3/9AT is an ultra-low capacitance, 1800 Watt rating, TVS Diode designed for ESD protection. This article will discuss the application field and working principle for the SMCG130A-E3/9AT.

The SMCG130A-E3/9AT is designed for use in areas that require signal line and data line protection against ESD or lightning-induced surges. The device provides electrostatic discharge protection (±15kV), in-circuit protection (35A peak pulse current capability for 1ms pulse) and lightning surge protection (5A peak pulse current capability at 8/20us pulse). This makes it ideal for high-speed data interfaces, such as Ethernet, USB, HDMI, VGA, and serial communication lines.

In addition, the SMCG130A-E3/9AT offers a low capacitance value of only 0.4pF, which helps maintain signal integrity while providing the required level of signal line ESD protection. This also makes it suitable for high-speed data and signal lines where long propagation delays and minimal signal reflections are required. The diode is available in a convenient 9-Pin array package, which allows for direct connection to the data line, or a flying-lead application.

The SMCG130A-E3/9AT uses an advanced low capacitance TVS diode structure to provide its high-performance protection. The device operates as a unidirectional clamp to absorb transient voltages. When an overvoltage or surge event occurs, the device will quickly clamp the voltage to a safe level, preventing voltage spikes and surges from damaging or disrupting the circuit\'s operation. The device is designed to shunt the excess energy to ground, thereby dissipating it away from the circuit.

The SMCG130A-E3/9AT is designed for use in a wide range of applications, including industrial, automotive, communications, consumer electronics, and IoT applications. It is suitable for a wide range of working temperatures, from -55°C to +125°C. The device is designed to provide ultra-low capacitance for maximum signal integrity. With its 1800 Watt rating, the device can handle both long term and short term power surges.

The SMCG130A-E3/9AT is an extremely reliable and robust TVS diode designed for use in a broad range of applications. With its low capacitance, high power dissipation rating, and high surge protection capability, the device can handle both ESD and lightning-induced surges, protecting critical components from damage and disruption. The device is available in a convenient 9-Pin array package, allowing for direct connection to the data line, or a flying-lead application.
