TVS diodes, also known as Transient Voltage Suppression diodes, are Zenner diodes that are designed to protect AC power sources and other electronic circuits from transient and transient voltages, such as electrostatic discharge and voltage surges. The P4KE27C-B is a TVS diode designed to protect sensitive electronic circuits from voltage surge. Below, we discuss the application field and working principle of the P4KE27C-B.

The P4KE27C-B is a unidirectional diode designed to protect sensitive electronic components from high voltage. It is used mainly to protect memory components, microprocessors and other sensitive IC components from electrostatic discharge, lightning and other voltage surges. The P4KE27C-B can handle a maximum working voltage of 27 volts. It is therefore suitable for protecting various AC and DC power sources, such as transformer ac outputs, automotive systems and computer equipment. The P4KE27C-B is available in both flat and small miniature packages and can be easily installed in circuits, making it a popular choice for a variety of applications.

The P4KE27C-B has a low leakage current with a maximum leakage current of just 0.1nA at 25°C. It also features high current capacity limit up to 400mA for 10/1000 μs pulse. The P4KE27C-B is best suited for protecting ICs that are sensitive to ESD. It is available in a variety of ESD energy dissipation ratings, from 15kV to 40kV.

The P4KE27C-B is a dynamic TVS diode. Its working principle is based on the Zener diode principle, which allows it to protect IC components from transient voltages. During a surge and over voltages, the P4KE27C-B will conduct when the threshold voltage is exceeded. The device is able to conduct a current spike and will then quickly clamp the voltage to protect sensitive ICs. Once the surge is over, the diode will switch off and the circuit will return to its normal operation.

In conclusion, the P4KE27C-B is a unidirectional TVS diode designed for AC and DC power sources. It is widely used for protecting sensitive components from ESD, lightning and voltage surges. The P4KE27C-B features low leakage current and high current capacity limit. It is best suited for protecting ICs that are sensitive to ESD and is available in a variety of ESD energy dissipation ratings. The device works on the Zener diode principle and is able to quickly clamp voltage during a surge.
