TVS (Transient Voltage Suppressor Diodes) are a type of semiconductor electronic devices of particular significance in the protection of electrical components from high-voltage spikes or surges. The P6KE8.2CHE3/73 device is an example of a TVS that enables the protection of electrical circuits against surges or overvoltage. This particular device is commonly used in mobile telecommunications, consumer electronics, set-top boxes, laptop computers, and a variety of other equipment.

The working principle of the P6KE8.2CHE3/73 device is to act as a double-edged sword, with both its anode electrodes and cathode electrodes exposed to the flow of current when applied an external voltage in excess of the device’s breakdown voltage. When the applied voltage exceeds the breakdown voltage of the device, the current is clamped at a safe level and the device becomes a short circuit and dissipates the damaging excess energy as heat. When the voltage drops below the breakdown voltage level, the current is re-clamped and the device is again kept in its normal off state.

The P6KE8.2CHE3/73 device is constructed of a highly doped silicon MOV (metal oxide varistor) designed for bidirectional surge overload clamping. It is surface mountable with a lead-frame termination, and has an operating voltage range of 5.0 to 8.2 volts. The device has excellent thermal stability and low clamping voltage characteristics, making it suitable for use in many different applications. It is able to tolerate temperature variations of up to -55 to +150°C and has a storage temperature range of -65 to +175°C. Additionally, it has an ESD rating of 8kV and is RoHS compliant.

Typical application fields of the P6KE8.2CHE3/73 device includes protection of signal lines from ESD/EFI, high voltage surge protection, consumer electronics, power supply clamping, and automotive applications. The device is used in these applications in order to provide protection from dangerous high voltage events, such as, electrostatic discharges, electrical fast transients, and electro-magnetic interference, which can be caused by voltage spikes or other external influences.

In summary, the P6KE8.2CHE3/73 device belongs to the TVS Diodesfamily and is used in many different application fields such as input/output signal protection, high voltage surge protection, consumer electronics, and automotive electronics. Its working principle involves the clamping of the current at a safe level when the applied voltage exceeds the breakdown voltage of the device, and the re-clamping of the current when the voltage drops back below the breakdown level. The device is highly thermal stable, has low clamping voltage characteristics, and is RoHS compliant.
