TVS, or Transient Voltage Suppressor, is a kind of device specially designed to protect circuits from damage caused by over-voltage, or voltage spikes. A TVS diode, such as the 1V5KE18A, is a device that is made up of three parts: a junction capacitance, a surge protection element, and a reverse recovery element. It is specially designed to protect circuits from over-voltage, or voltage spikes.

The junction capacitance of a 1V5KE18A is made up of two parts, one of which is the semiconductor junction which stores electric charge. This junction also acts as a buffer between the two other parts of the device. The surge protection element protects the device from large changes in voltage, while the reverse recovery element helps to reverse the current flowing through the device if it is ever overloaded.

This device is very useful in applications where it is necessary to protect circuits from high-voltage spikes, such as in automotive electronics, air traffic control systems, and computer networks. It is also used in telecommunications systems where it helps to protect the transmission line. In medical electronics, the 1V5KE18A is used to protect sensitive circuits, as it can prevent electrical sparks and fires.

The 1V5KE18A is capable of handling up to 5kV of transient over-voltage, which is enough to protect most circuits from damage caused by occasional voltages spikes. The device also features a wide operating temperature range and is able to handle a wide range of currents, making it suitable for many different applications. It is an ideal choice for applications that require high surge protection capabilities, as the device can handle up to 5 times the normal operating current.

The working principle of the 1V5KE18A is relatively simple. When a sudden increase in voltage occurs, the device’s surge protection element is triggered, which causes the current to be diverted away from the sensitive components of the circuit, protecting them from damage due to the sudden over-voltage. When the over-voltage is reduced, the device automatically returns the current to its original path.

In summary, the 1V5KE18A is a TVS diode which is designed to protect circuits from voltage spikes. It is capable of handling up to 5kV of transient over-voltage and has a wide operating temperature range. The device’s working principle is such that it is able to divert current away from sensitive components when an over-voltage occurs, and automatically returns it to its original path when the voltage has been reduced. This makes it an ideal choice for applications that require high surge protection capabilities.
