Transient voltage suppressors (TVS) diodes offer excellent current surge protection in many different applications. 1V5KE22CA is one of the many transient voltage suppressor (TVS) diodes that can be used in many applications. TVS diodes can protect a wide range of electronics from voltages that may otherwise cause damage or destruction to the components.

The 1V5KE22CA TVS diode is a bi-directional device, meaning it can protect against voltage transients pulsing in either direction. The 1V5KE22CA offers improved power dissipation with more than 1.0W of power withstanding capability, making it ideal for protecting components from high voltage transients such as lightning strikes and other sources. It is designed for high-speed transient voltage protection. The 1V5KE22CA diode operates typically 75V with a peak pulse power of 3kW.

The 1V5KE22CA application field and working principle are mainly used for outdoor equipment, telecom equipment, and all other AC/DC power supply systems. It is widely used for lightning protection, surge protection, voltage spike suppression, and ESD protection. Its working principle is based on the junction breakdown effect. When a certain voltage is applied across the junction, the potential barriers of the junction will wear off due to thermal effects and heavy current will flow through the junction, thus offering effective transient voltage protection.

In the practical application of 1V5KE22CA transient voltage suppressors, it should be installed on the power supply side of the equipment, and the distance between the TVS tube and the protection device should be as close as possible. The TVS’s working voltage should be as close as possible to the voltage of the equipment and the rated clamping voltage should not exceed its stand-off voltage. It can also be used in surge protection groups where multiple 1V5KE22CA are installed in a series at different points of the system for redundancy or for broad coverage of multiple components.

The 1V5KE22CA provides excellent static and transient surge protection against high-energy transients of either polarity. Its robust current handling capability ensures excellent performance against high-current transients, and its high reliability ensures consistent long life. It is an excellent choice for surge protection of a wide variety of applications.
