The 15KPA150CE3/TR13 is a part of the TVS- Diodes family. It is a three lead, bidirectional, low capacitance, silicon independent voltage transient suppressor, designed to protect high speed data lines. It has a low breakover voltage of 15V and a power dissipation of 400W.

The 15KPA150CE3/TR13 is used for circuit protection against electrical overstress (EOS) in automotive electronic systems. It can be used for surge protection of data bus lines and other sensitive electronics in the resistor controlled feeding circuit (power line). It also provides ESD protection from EMC noises.

The 15KPA150CE3/TR13 has two main active components, which provide and control its functions. These are a pair of Zener diodes and a pair of transistors. The Zener diode is the main component, which controls the application of the transistor pair in order to limit voltage overshoot, while allowing the device to withstand higher surge currents. The transistor pair is used to provide current flow in the opposite direction of the main components.

The working principle of the 15KPA150CE3/TR13 is simple. It functions as a voltage regulator, so it can sense when the voltage gets too high and act to reduce it to an acceptable level. As the voltage rises, the device is triggered and the pair of Zener diodes form an avalanche breakdown, allowing current to flow in the opposite direction. This current then passes through the transistor pair, which controls the temperature and limits the surge. This process suppresses the overvoltage event and keeps the line voltage regulated at a predetermined level.

The device also features an integrated overvoltage protection circuit, which operates when the voltage increases above its threshold. A simple voltage clamp will be activated, reducing the voltage to an acceptable level and allowing the data line to function correctly. Additionally, the device provides ESD (electrostatic discharge) protection, ensuring the line is protected from any static discharge.

The 15KPA150CE3/TR13 is a useful and reliable component for a range of automotive and other applications. It features a low breakover voltage, power dissipation and ESD protection, making it suitable for a range of applications. The simple working principle and integrated protection circuitry make it an ideal choice for circuit protection.
