TVS or transient voltage suppression diodes are two-terminal, nonlinear forges designed to protect electronic components from high-voltage, high-energy discharges, such as electrostatic discharge and power surges. This type of component is particularly important for electronic circuits that are routinely exposed to high voltages and/or unpredictable voltage shifts. 1.5KE15C-B is a popular type of transient voltage suppression diode.

The 1.5KE15C-B diode has a breakdown voltage of 15V with a reverse leakage current of 10mA. It is a unidirectional component and can be used to protect electronic components from high voltage transients. It is constructed from a single NPN transistor with two zener diodes and housed in a 125mil DO-50 package. The 1.5KE15C-B diode is particularly effective in applications that require protection from electrostatic discharge (ESD), or a sudden surge in voltage or current.

1.5KE15C-B diode\'s working principle is based on the breakdown voltage or breakdown potential. This voltage at which an electric current passes through a diode is called its breakdown voltage. When the voltage applied across the diode exceeds the breakdown voltage, the current passes through it, due to the avalanche effect. The avalanche effect is caused by electron-hole pairs in the diode increasing in number as the voltage across the diode rises. The resulting current surge is called an avalanche current.

The 1.5KE15C-B diode is used in many different applications. It is commonly used in telecommunications, power supply, automotive, industrial, and medical applications. In telecommunications, for example, the diode protects the circuitry and components from spikes, surges, and electrostatic discharge that can damage the circuit. It is also used to protect automotive and industrial systems from voltage transients due to lightning, electrostatic discharge, or other sources. In medical equipment, the diode can prevent voltage spikes or surges from disrupting the sensitive electrical components.

In conclusion, the 1.5KE15C-B is a robust transient voltage suppression diode used in a variety of applications. It is able to protect sensitive electronic components from high voltage transients and surges by regulating the current passing through the diode. By correctly selecting the appropriate single NPN transistor coupled with two zener diodes, the 1.5KE15C-B diode can provide reliable protection from a variety of electrical threats.
