Introduction

TVS (Transient Voltage Suppression) diodes are designed to protect circuits and systems from surges and spikes in voltage caused by electrostatic discharges (ESD), inductive switching of large electrical loads, lightning strikes and other high-voltage transients. The P6KE6.8A (also known as P6KE68A) is a general-purpose unidirectional TVS diode that belongs to a family of semiconductor protection devices known as Transient Voltage Suppression (TVS) diodes. These devices are commonly used for protecting expensive equipment from the effects of transients.

P6KE6.8A•Application Field•

The P6KE6.8A is well suited for the protection of electronic applications including: computer systems, telecommunications, process control, audio/video, office equipment, and automobiles. The device can be used to protect sensitive components in a variety of voltages that may be exposed to voltage transients, such as AC lines, USB ports, HDMI ports, and VGA ports. Additionally, the P6KE6.8A can be used in appliances, medical equipment, consumer electronics, industrial equipment, and automotive applications.

P6KE6.8A•Working Principle•

When a transient voltage spike occurs (due to ESD, lightning, or inductive switching), the P6KE6.8A is triggered into conduction. The diode acts as a short circuit, clamping the voltage at a safe level and helping to avoid device damage. The P6KE6.8A’s unidirectional design ensures that the device will only conduct current in one direction and will not create a short circuit condition during normal operation.The P6KE6.8A can be used in either unidirectional or bidirectional applications. For unidirectional applications, the P6KE6.8A can be connected in series with the load, while in bidirectional applications, it can be connected in series with both the positive and negative lines.The P6KE6.8A offers a high degree of protection against voltage transients in a variety of different voltages, including 6.8 V for unipolar applications and 6.8 V for bipolar applications. The device is designed to remain off until the voltage reaches the clamping voltage level. At this level, the TVS diode activates and begins to conduct current up to the maximum peak pulse current rating. The P6KE6.8A can also be used in high-speed applications, such as those found in USB and HDMI ports.

Conclusion

The P6KE6.8A is a general-purpose TVS diode that is designed to protect electronic circuits and systems from surges and voltages caused by ESD, lightning, and inductive switching of large electrical loads. It is well suited for the protection of electronic applications such as consumer electronics, industrial equipment, appliances, medical equipment, audio/video, automotive, and office equipment. The P6KE6.8A is capable of providing protection against voltage transients in a variety of different voltages and offers both unidirectional and bidirectional protection. By utilizing the P6KE6.8A, engineers can create reliable systems that are protected from the effects of high-voltage transients.
