Introduction to TVS - Diodes and 1.5KE10CHE3/54

TVS - Diodes, otherwise known as unidirectional transient voltage suppressors, are specially designed diodes used for protecting electronic components from high voltage transients, commonly known as electrical surges or sparks. They are generally used in consumer electronics, automotive, medical, and industrial control applications. The 1.5KE10CHE3/54 is a typical TVS diode that is widely used in these applications.

Application Field

TVS-diodes find applications in a variety of electronic and electrical areas. They are especially useful in high voltage, high frequency applications, as well as those dealing with cable or wiring which are prone to outside electrostatic discharges. In automotive applications, they are used to protect car electronics from high voltage transients and protect passengers from electrostatic discharge. Other applications of TVS - Diodes include consumer electronics, medical systems, industrial motor controls, military/aerospace, and telecommunications.

Working Principle

TVS - Diodes, just like any other semiconductor diode, consist of N (negative) and P (positive) doped regions connected together. When normal operating voltages are applied across the device, current flows from the P to the N side and the diode behaves like an ordinary, non-conductive diode. However, when a transient voltage signal, or a high surge, is applied across the device, current will not flow, and the diode is triggered into a very low resistance state. This is known as the “avalanche effect”. The diode then quickly conducts current in the opposite direction, providing a short circuit between the two sides. This prevents the larger pulses of current from entering or exiting the system.

Conclusion

TVS - Diodes are important and essential components for movies and protecting device, especially when it comes to high voltage and high frequency applications. The 1.5KE10CHE3/54 is one of the many widely used TVS diodes. It has a low capacitance junction, making it ideal for low frequency noise and transient protection, and can handle surge currents of up to 54 A. This makes it ideal for the majority of electronic and electrical protection applications.
