P4KE6.8CHE3/54 is a type of Transient Voltage Suppressor (TVS) diode which is used to provide overvoltage protection in order to defend sensitive electrical and electronic equipment shortages from overvoltage transients. This device is a unidirectional and bidirectional form of diode that helps protect circuits from voltage spikes.

Application Field:
The P4KE6.8CHE3/54 is a 6.8V TVS diode which is designed to protect circuits in automotive, telecom, industrial, consumer and personal computer applications. Owing to its robust design and small form factor, it is increasingly being used in applications where high voltage protection, reliability, and form factor are important design considerations.

Working Principle:
The P4KE6.8CHE3/54 works by clamping the voltage transient at a predetermined breakdown voltage, thus preventing damage to the load circuit. When an over voltage transient appears, the diode rapidly turns on and acts as a low resistance that shunts the voltage and current to ground. This action clamps the voltage transient at the diode’s breakdown voltage. As a result, the current remains at a safe level until the overvoltage transient dissipates.

Features:
The encapsulated P4KE6.8CHE3/54 offers low leakage and fast response time. It is designed to withstand high ionizing radiation levels for over five Mrads, making it ideal for aerospace applications. It is also RoHS 2 compliant and provides strong ESD protection. The surface-mount package enables easy assembly in a PCB.

Conclusion:
The TVS diode used in a P4KE6.8CHE3/54 form offers an effective and reliable solution for protection against overvoltage transients. This diode can be used in a variety of applications and offers excellent performance and features. It is easy to assemble and highly reliable.
