1.5KE12ATR is a unidirectional bi-directional transient voltage suppressor (TVS) diode. It is one of the most important components in the protection of electronics from transient overvoltage caused by ESD (electrostatic discharge) or other sources. The 1.5KE12ATR diode is designed to protect against transient voltages up to 14V. It has an RMS power rating of 1.0W, and a maximum peak forward surge current of 10A.

The 1.5KE12ATR diode has a low clamping voltage that makes it especially suitable for protecting specialized electronics, such as those used in automotive applications, where it is especially important to limit the amount of voltage that passes through the circuit. The 1.5KE12ATR diode also has a fast response time, making it suitable for applications in which fast response times are important for ensuring that transient overvoltage is quickly suppressed.

The working principle of the 1.5KE12ATR diode is fairly simple. When the voltage across the diode exceeds the breakdown voltage of the diode, it will begin to conduct and limit the voltage that passes through it. The breakdown voltage of the 1.5KE12ATR diode is typically between 6V and 12V, depending on the ambient temperature. The diode will also begin to conduct if the voltage across it exceeds the avalanche voltage, which is typically around 14V. When the diode is conducting, it will dissipate the excess energy as heat, ensuring that the circuitry downstream of the diode is not damaged by the transient overvoltage.

The 1.5KE12ATR diode is a key component in many applications where transient overvoltage protection is essential. It is often used in automotive and industrial applications, as well as in consumer electronics such as printed circuit boards (PCBs). In addition, the 1.5KE12ATR diode is often used in power supplies, telecommunications equipment, and medical equipment.

Overall, the 1.5KE12ATR diode is an important component in many applications where transient overvoltage protection is essential. It is a cost effective way to protect sensitive electronic components from damage caused by ESD or other sources of transient overvoltage. The diode has a low breakdown voltage and a fast response time, making it ideal for applications in which fast response times are important.
