TVS (transient voltage suppressor) diodes are electrical devices used for protection of sensitive electronic components, such as circuits, cables, and wiring. They are typically used to prevent voltage spikes from damaging circuitry or cable insulation. They can also be used in applications where a controlled amount of current is required to be passed through a component. The SMP28-E3/85A is a silicon junction TVS diode designed for use in applications where a large amount of current might be required to be passed through the component.

The SMP28-E3/85A is a Zener breakdown diode that features a low on-state resistance, high surge capability and low capacitance over a wide frequency range. It is designed for use as a voltage protector in electronic circuits, such as power supplies, amplifiers, and other sensitive electronic components. The operative principle of the SMP28-E3/85A is based on a reverse breakdown voltage. When this reverse breakdown voltage is reached, the diode begins to conduct in the reverse direction and a large amount of current is allowed to pass through the component.

The SMP28-E3/85A is ideal for applications where a high amount of current is desired as it has a reverse breakdown voltage of 85 volts. Additionally, the diode offers excellent surge handling capabilities with a peak pulse current of 4500 A. The reverse leakage current of the diode is relatively low (< 1uA) and the forward leakage current is also low (> 0.1uA).

The SMP28-E3/85A is suitable for use in high voltage and high current applications in a wide range of environments, such as automotive, industrial, and consumer electronics. It is typically connected in series with the power line to provide surge protection for sensitive components in electronic circuits, and can also be used in automotive applications. The SMP28-E3/85A is capable of handling high voltages and currents, and is designed to be rugged and reliable, making it ideal for use in high power and high amplitude applications.

In conclusion, the SMP28-E3/85A is a silicon junction TVS diode designed for use in applications where a large amount of current might be required to be passed through the component. It features a low on-state resistance, high surge capability and low capacitance over a wide frequency range, and is suitable for use in automotive, industrial, and consumer electronic applications.
