TVS - Diodes

A TVS diode, also known as a transient-voltage-suppression (TVS) diode, is a type of solid-state diode used to protect circuits, such as VLSI integrated circuits, from high-voltage transients. The P4KE8.2CA-E3/73 is a TVS diode that is specifically designed for applications that require a high level of protection from high-energy transients. This diode is capable of suppressing voltage transients to a level that will not damage sensitive electronic components.

Application Field

The P4KE8.2CA-E3/73 is designed for use in applications that require a high level of protection against high-energy transients. These transients can be caused by lightning strikes, power surges, and other disruptions in electrical power. This diode is also ideal for protecting sensitive electronic components, such as DC motors, integrated circuits, and transformers.

Working Principle

The P4KE8.2CA-E3/73 is designed to protect sensitive electronic components from damage due to high-voltage transients. When a high-voltage transient occurs, the diode will conduct electricity in the reverse direction, effectively clamping the voltage to a safe level. The diode is designed with a substantially low drain-to-source breakdown voltage and a low clamping voltage, providing optimal protection without degrading the performance of the circuit.

Advantages

The P4KE8.2CA-E3/73 has several advantages over other TVS diodes. The low clamping voltage of this diode ensures that the power supply voltage of the circuit remains within safe limits, protecting sensitive electronic components from damage. The diode is capable of suppressing transient voltage peaks up to 8.2 volts, which is well above the rated voltage of the circuit. The diode also has a very low drain-to-source breakdown voltage, ensuring that current passes through the diode without degradation.

Conclusion

The P4KE8.2CA-E3/73 is an ideal solution for applications that require a high level of protection from high-energy transients. Its low clamping voltage ensures that the power supply voltage of the circuit remains within safe limits, and its low drain-to-source breakdown voltage ensures that current passes through the diode without degradation. This diode is designed for use in applications such as DC motors, integrated circuits, and transformers, providing a high level of protection against high-voltage transients.
