20KPA180C-B Circuit Protection

TVS - Diodes

The 20KPA180C-B is a transient voltage suppressor (TVS) diode. Its primary purpose is to protect sensitive electronic components from voltage spikes in power sources. The device works by quickly clamping the voltage to a safe level, thus preventing any damage from occurring. It is widely used in applications such as consumer electronics, automotive, industrial, and telecommunications.

Application Fields

The device is commonly used in a variety of electronic components and systems. It is an effective protection device for power controllers, embedded systems, microcontrollers, communication receivers, FPGAs, transformers, AC adapters, and other sensitive equipment. For example, in automotive systems, it can protect against power surges caused by faulty wiring or faulty components. It is also widely used in industrial systems, where it can protect against voltage surges from lightning strikes or power spikes.

Working Principle

The 20KPA180C-B works by quickly redirecting the voltage away from the sensitive components and dissipating it to ground. It is made up of two diodes connected in parallel, with one diode forward-biased and one diode reverse-biased. This arrangement allows the device to quickly switch between forward and reverse states when a high voltage surge is detected. When a voltage surge is detected, the forward-biased diode will quickly clamps the voltage to a safe level, thus preventing any damage from occurring. The reverse-biased diode is then activated to dissipate the excess energy and to avoid any voltage bounce-back. This ensures that the circuit is quickly and safely protected from any voltage surge.

The 20KPA180C-B is a versatile device and is available in a variety of models and packages. It is also suitable for both AC and DC applications. This allows it to be used in a wide range of applications, from automotive to consumer electronics.
