TVS – Diodes form an essential part of power systems, protecting them from spike and surge. The SMC5K17AHM3/H TVS diode is applied in high-speed ports on computers and other electronic equipment for protection against electrostatic discharge (ESD), electro-magnetic interference (EMI) and external disturbances. It is also widely used in communication ports, USB ports, audio signals and LCD displays. It is an ideal choice for high level of environmental protection.

The main function of the SMC5K17AHM3/H TVS diode is able to protect the connected circuit from overvoltage, ESD and EMI. It provides a low capacitance, low clamping voltage, and fast response time. The fast response time enables the TVS diode to provide exceptional ESD protection, which can absorb a large amount of energy and clamp the voltage within the specified range. It is designed to dissipate transient energy away from the circuit and prevents damage caused by overvoltage.

The working principle of the SMC5K17AHM3/H TVS diode is based on the guiding principle of diode clusters, or the avalanche effect, as the breakdown voltage of the diode is reached, the avalanche initiates and enables current to flow directly to ground. This is very similar to the concept of induction in electrical circuits, where an energy source is connected to two separated paths, and the energy induced in one path is forced down the other path. It is the same principle for the diode, when the ultimate breakdown voltage is reached, more and more current will flow directly to ground.

The SMC5K17AHM3/H features typical maximum reverse stand-off of 5KV, low profile electrical components, low capacitance and a low clamping voltage. With an operating temperature of up to +125 degree Celsius, it is ideal for use in harsh environmental conditions and for applications where high speed is required. It also has an extremely low clamping voltage that allows for improved reliability and better surge protection.

In conclusion, the SMC5K17AHM3/H TVS diode is a very versatile and reliable device for applications in computers, communication ports, USB ports, audio signals and LCD displays. It has low capacitance, fast response time and low clamping voltage. Additionally, it is designed to dissipate transient energy away from the connected circuits and prevent damage from overvoltage. It provides exceptional ESD protection, allowing for improved reliability and better surge protection.
