《TVS - Diodes》1.5KE6.8A/54 application field and working principle

Transient voltage suppressor (TVS) diodes are unidirectional solid-state devices designed to protect against voltage transient and overvoltage conditions. They are primarily used to protect electrical and electronic components against transient surge voltages, but can also be used to clamp overvoltage. 1.5KE6.8A/54 is one type of TVS diode, whose application field and working principle will be discussed in this article.

Application Field of 1.5KE6.8A/54

1.5KE6.8A/54 is a diode designed for transient voltage suppression against lightning or other surge voltage. Voltage range is 6.8V, with a maximum peak pulse power rating of 1500W, it can also be used in low power capacitive loads. Typical applications of 1.5KE6.8A/54 include automotive electronics, industrial and medical equipment, telecommunication and IT systems, and audio/video equipment.

Working Principle of 1.5KE6.8A/54

TVS diodes are two-terminal, solid-state devices that can be connected to a circuit in either direction. The 1.5KE6.8A/54 includes two back-to-back avalanche diodes. This type of diode has a structure with extremely low on-state resistance and low leakage. When the bidirectional input voltage exceeds the peak inverse voltage (PIV) rating, the avalanche diode is triggered, allowing the current to flow through the diode and clamping the voltage. After the surge ends, the diode automatically returns to its low-impedance state.

Conclusion

1.5KE6.8A/54 is a type of TVS diode designed to protect sensitive electronic components from transient surge voltages. This diode has a wide range of applications, including automotive electronics, industrial and medical equipment, telecommunication and IT systems, and audio/video equipment. The working principle of the 1.5KE6.8A/54 is simple and efficient - when a voltage surpasses the PIV rating, it automatically clamps the voltage and then returns to its low-impedance state when the surge is over.
