TVS - Diodes is a type of electronic components commonly used in today\'s electronic products. 15KP120CA-TP is one type of TVS diode, composed of the thermally sensitive positive temperature coefficient (PTC) and the reverse breakdown diode. This kind of diode has a wide range of applications, such as line protection, computer protection, and surge immunity protection.

The application field of 15KP120CA-TP is mainly for over-voltage protection of low voltage and small current lines, such as computer motherboard, power supply, LCD displays, communication lines, etc. The working voltage range of this device is 18V-24VDC, continuous working current under 70A, and maximum surge current above 1000A. It has good compatibility, fast response time and flexibility, which make it suitable for line protection over the voltage range.

The working principle of 15KP120CA-TP is based on the combination of PTC thermistor and zener diode to provide over-voltage and over-current protection. Under normal circumstances, the thermistor conducts current, with a resistance value of several ohms or tens of ohms. When over-voltage or over-current occurs, the thermistor resistance increases rapidly, causing the temperature to rise and the current to reduce instantly, thus protecting the system.

Besides the function of over-voltage and over-current protection, 15KP120CA-TP can also protect several lines from cross-type overloading. The device is equipped with a multi-lead termination technology. In order to break or reduce the current loop between multiple lines, the current loop area can be increased by using a post-applied thermal plastic standoff design with four terminal leads. The four terminal leads provide contact between the PC board and device, which helps to dissipate the heat generated in the device for safer use.

15KP120CA-TP is a reliable, high performance and cost effective device, suitable for different types of computer peripherals. It has fast response time, excellent resistance capability and good durability, ensuring seamless operation of the equipment. The device is designed with over-voltage and over-current protection functions, making it a nice choice for protecting delicate electronic components.
