TVS-diodes are a type of component commonly used in electronic circuits to protect the device from voltage spikes or electromagnetic disturbances. The SMBJ28-E3/52 is one such TVS-diode that has a variety of applications due to its unique features.

The main purpose of a TVS-diode is to limit the peak voltage on a circuit line in order to protect other components connected to it. This type of diode works by conducting current when the voltage exceeds a specific level. The SMBJ28-E3/52 is a type of TVS-diode with a 28V working voltage and a breakover voltage of about 52V. It is designed to endure continuous reverse voltage peaks of up to 28V and short-term peak voltages of up to a maximum of 75V. This diode\'s thunder-flash energy is also rated at 0.5J, its operating temperature range is -65 to +175 degrees Celsius, and its response time is 0.01ns.

The SMBJ28-E3/52 has a number of advantages over other TVS-diodes. For example, due to its high-reverse voltage, it can be used in applications with higher reverse voltage requirements. The diode also has a low peak forward voltage, which makes it efficient at dissipating power in the circuit. Furthermore, its fast response time makes it suitable for fast-changing applications. Additionally, its low leakage current ensures that the device remains protected from sudden in-rush currents.

The SMBJ28-E3/52 is typically used for providing surge protection in various applications. This includes protection of communication lines, signal lines, and data lines that require high transients protection. Additionally, the diode can also be used in other applications such as over-voltage protection circuits, electrostatic discharge protection circuits, and power distribution systems.

The working principle of the SMBJ28-E3/52 is quite simple. When the voltage across the device exceeds its breakover voltage, the diode begins to conduct current. This current then flows through the device, thereby protecting the rest of the circuit from the excess voltage. The current flow is limited by the diode\'s reverse voltage, as well as its resistance.

In conclusion, the SMBJ28-E3/52 is a type of TVS-diode that has a wide range of applications due to its high breakover voltage and low peak voltage. It is also ideal for surge protection applications due to its fast response time and low leakage current. Furthermore, its working principle is simple and efficient, making it a highly reliable device for protecting various electronic circuits.
