1.5KE16C-B is a popular thyristors for unidirectional protective device in the field of TVS-Diodes. It is a protection device and the most significant application of this kind of thyristors is preventing DC power supplies from ESDs (electrostatic discharges). It can also protect against inductive transients, lightning, and other surge sources.

The 1.5KE16C-B application field can be explained as a two-step process. First, the thyristor is triggered by an external voltage source that exceeds the breakdown voltage. When this occurs, a forward gate current will pass through the semiconductor. This current will cause a commutation device, which is typically a diode, to be switched on, thereby creating a closed loop to provide the necessary protection.

The working principle of the 1.5KE16C-B is based on the thermionic effect of the thyristor. This is a process where electrons are freed from one metal material and can travel freely through the device\'s semiconductor material. As the current increases across the device, the electrons are conducted to another metal material, thereby creating a closed loop. This closed loop will provide the necessary protection and help to prevent the power supply from overvoltage or ESDs.

The 1.5KE16C-B also works differently than most other thyristors. Instead of having an external contact for triggering the device, it utilizes a special mechanism of the device itself. When exposed to a voltage that exceeds the breakdown voltage, the device will conduct, creating a current loop that will provide the necessary protection. This makes the 1.5KE16C-B an ideal choice for protecting against ESDs, lightning, inductive transients, or other surge sources.

Overall, 1.5KE16C-B\'s are an important component of the TVS-diodes. It is part of the thyristor family, and is often used as a protection device against ESDs, lightning, inductive transients, or other surge sources. The thermionic effect of the thyristor and its external contact-less triggering mechanism are critical components of its working principle.
