SLVU2.8-8A1 Circuit Protection

TVS – Diodes application field and working principle of SLVU2.8-8A1

Transient Voltage Suppression (TVS) Diodes are semiconductor devices specifically designed to protect against sudden Voltages and spikes. These devices protect components, equipments, data lines, or power lines from destructive electrostatic discharges (ESD) and static electricity. The SLVU2.8-8A1 series belongs to this category.

Application Fields

SLVU2.8-8A1 has a wide range of applications in different industrial and consumer electronic products, alongside military, avionics and communications equipment. The product is a popular choice for end-users due to it’s robustness, efficient size and low capacitance.

SLVU2.8-8A1 can be employed in computer keyboards, automotive electronics, USB lines, portable electronics, automotive navigation systems, Aerospace and defense systems, and many power line applications. It can also be used on its own or as part of assemblies and housings.

Working Principle

The SLVU2.8-8A1 has a symmetrical breakdown voltage of 28 volts. It consists of a doped semiconductor material with an anode and a cathode. When a voltage is applied, the anode-cathode junction becomes forward biased, meaning that current will start to flow from one to the other. The operation of the diode is relatively simple. When a surge in voltage (above the breakdown voltage) is applied, the device will enter a conducting state. This will result in clamping the applied voltage to the breakdown voltage. This results in current flowing out of the device. As the applied voltage drops below the breakdown voltage, the diode will enter a non-conducting state, and will not conduct any current. The device will remain in this state until a further surge in voltage is applied.

The SLVU2.8-8A1 device is particularly well suited for applications which require a high level of protection against ESD and electrostatic fields. The low capacitance ensures that there is no distortion of high frequency signals. This makes it particularly well suited for data and signal line applications.

Conclusion

The SLVU2.8-8A1 series is a reliable and robust device for protecting against sudden voltages and spikes. Its versatile range of applications is extensive, from automotive to aerospace applications. The device has a low breakdown voltage and a low capacitance, ensuring that high frequency signals are not distorted. It is a practical and reliable solution for applications which require protection from transient overvoltages.
