With the rapid development of communication technologies, the demand for TVS - Diodes is increasing. The 30KP108A-TP is a widely used TVS-Diode which is ideal for protecting both data lines and power supply lines against electromagnetic interference. In this article, we will discuss the application field and working principle of 30KP108A-TP.

Application field

30KP108A-TP is mainly applied in communication lines, which are used in DSL for digital subscriber line, CATV for community antena television, the IEEE Ethernet, UWB for ultrawideband, the USB, the IEEE 802.11, and more. This diode is also used in the automotive up/down links in the communication systems for protection.

The 30KP108A-TP is also used to protect power supply lines of 12V DC equipment. This diode is primarily used to protect equipment from overvoltage on the power supply line, personnel from electric shock, and equipment from damage due to overvoltage.

Other application fields include the protection of computers, control systems, I/O interfaces, and telecom equipment from ESD and EFT. This diode can also provide voltage clamping for power system circuits such as solar panels, batteries, and other voltage-sensitive components.

Working principle

The 30KP108A-TP is part of the breakdown diode type TVS-Diodes. It is a bi-directional diode with two different voltage levels (5.6V and -7.3V for the 30KP108A-TP). This diode works by having a high voltage trigger level and a low voltage clamping level. When the voltage reaches the trigger level (5.6V or -7.3V for the 30KP108A-TP), the diode quickly clamps the voltage at the low voltage clamping level (5.0V or -6.5V for the 30KP108A-TP) to protect the treated circuit from overvoltage.

The 30KP108A-TP also has an architecture designed to withstand transient overvoltage and high frequencies of current
