TVS Diodes, or Transient Voltage Suppressors, are widely used in today\'s consumer electronics and powering systems to effectively limit voltage transients, which are caused by electrostatic discharge (ESD), lightning, and other electrical transients. As an important part of the circuit, they protect the system from damage by providing a short circuit over a wide range of currents for a specified period of time, thereby protecting the system from overvoltage and other electrical transients. As such, TVS diodes are used in a variety of applications, including automotive, consumer electronics, communications, and power systems.

The SMA5J28-E3/61 is a type of TVS diode, which is optimized for ESD protection and has a high-speed response. The device features a low breakdown voltage of 28V, a low clamping voltage of 14.2V, and a response time of 1 nanosecond. It also features a low-impedance rectifying structure, ESD-capable and secondary breakdown protection, and a wide operating temperature range of –55°C to +125°C. It is suitable for use in data lines and printer connections, as well as other sensitive lines.

The SMA5J28-E3/61 is widely used in consumer electronics. Its ability to handle very fast transients makes it ideal for high-speed data lines and electrically sensitive equipment. It is also suitable for use in communications and electric networks, as its low impedance design enables it to reduce signal reflections and minimize crosstalk. Another important application is in automotive and equipment industries, where it is used to protect against ESD and electrical transients.

In terms of working principle, the SMA5J28-E3/61 is a simple zener diode which works by constraining the electric field within a given area during operation. It functions by conducting overvoltages to reduce their magnitude, and by providing a low-impedance path for typical transient currents. The device contains several individual diodes connected in series, which helps to provide clamping protection for several different breakdown voltages.

The SMA5J28-E3/61 also features an internal over-current protection circuit, which prevents it from shorting or developing a high resistance if an excessive current is encountered. The device also has a thermal shutdown function, which is activated when it reaches a certain temperature. This helps to prevent any further heat accumulation and to protect the device from damage.

Overall, the SMA5J28-E3/61 is a reliable and high-speed TVS diode optimized for ESD protection in consumer electronics, communications, automotive and power systems. It is highly effective in reducing voltage transients and protecting against ESD and electrical transients. It features a low impedance rectifying structure, a wide operating temperature range, and an internal over-current protection circuit and thermal shutdown function for added protection. It is an ideal choice for protecting sensitive systems from voltage transients and ESD.
