TVS - Diodes are electronic components designed to protect other electronic components from damage due to electrostatic discharge (ESD). These devices have two layers of protection: one layer designed to handle the current of the ESD event, and a second layer designed to absorb the energy of the event. The P4KE400C is a diode in the TVS family specifically designed to protect high speed circuits from electrical transients, like those caused by ESD. Its working principle is based on a reverse-biased PN junction to divert the ESD current by clamping the voltage to a predetermined level during an ESD strike.

The P4KE400C helps protect circuit components from voltage transients by providing an internal sense voltage and leakage current. The sense voltage helps the diode recognize when an ESD event has occurred, and the leakage current allows the circuit to remain functioning afterwards. This diode also has low capacitance, which helps to reduce the amount of electrical noise that can be coupled onto the protected circuit.

The P4KE400C\'s application field include a wide range of industries and applications. It is particularly useful in consumer electronics, due to its ability to protect the products from ESD and other electrical transients. It is also widely used in industrial and military applications, due to its robust design and reliability. This diode can be found in a variety of products, such as: computers, cell phones, game consoles, medical systems, communication and audio systems, automotive systems, and more.

The P4KE400C has a wide operating temperature range (-55 to 125°C), which makes it well-suited to a variety of different environments. This capability allows the device to be used in both commercial and industrial applications. Additionally, it has a high surge current capability (3,500 A peak pulse current), which helps to protect the circuit from high voltage transients.

The P4KE400C is a reliable and durable device that can provide protection from ESD and related transients. It has a wide operating temperature range, allowing it to be used in a variety of environments. Additionally, its high surge current rating ensures that the protected circuit is safe from high voltage electrical transients. With its wide application field and reliable working principle, the P4KE400C is an excellent choice for many different protection applications.
