TVS - Diodes, also known as transient voltage suppressors, are components that protect electrical circuits from damage caused by transient voltage. The P4KE160CHE3/54 is a unidirectional Transient Voltage Suppressor (TVS) diode that is designed to protect sensitive electronic components from electrostatic discharge (ESD), inductive switching, lightning and other types of transients.

The P4KE160CHE3/54 is an ultra-low profile package, allowing for a reduced height profile of low-voltage applications. It features a 5mm x 5mm SO-8 package that enables a 25% reduction in board space and weight compared to the standard leaded package. Rated for a peak pulse power of 160W (@ 8/20µs pulse width), the P4KE160CHE3/54 is suitable for general-purpose application. Its ultra-wide operating voltage range of 7.0 to 420 volts, combined with its low junction capacitance, make it ideal for protection against ESD.

This device is designed to safely diverge electrical energy from ESD and other transients away from sensitive components. It works by regulating an incoming voltage surge or spike to a safe level before it reaches a sensitive electronics. The P4KE160CHE3/54 can also suppress high-frequency noise on data and signal lines.

The P4KE160CHE3/54’s working principle is based on the avalanche breakdown effect that occurs when a reverse-biased PN junction reaches its peak, or breakdown, voltage. When a transient voltage or surge greater than the PN junction breakdown voltage is applied to the TVS in the reverse polarity, a large number of carriers are created that can easily conduct away the impulse current.

The P4KE160CHE3/54 is suitable for a variety of applications, including automotive, consumer electronics, computers, servers, industrial and telecommunication equipment. It can be used for protection against ESD, inductive switching, fast transients, over-voltage transients, and up to 160 watts of peak pulse power. Apart from suppressing transients, the P4KE160CHE3/54 can also reduce high-frequency noise on data and signal lines.
