TVS diodes are designed to protect sensitive electronic equipment from voltage transients induced by lightning and other electrostatic discharge (ESD) events that can exceed the level of thousands of volts.

The MP5KE20CA is an general purpose transient voltage suppressor (TVS) manufactured by ROHM Semiconductor. This device is a two-terminal, rapid response, bidirectional suppressor diode. It is designed to protect sensitive electronic equipment from voltage transients induced by lightning, electrostatic discharges (ESDs) and other sources. This device has a 5.0 ampere peak pulse current (ITSM) rating and an 20V maximum stand-off voltage rating.

The MP5KE20CA can be used in a variety of applications, including automotive, consumer electronics, industrial and telecommunications. In automotive applications, it is used to protect control systems, ECUs, and other automotive electronics from voltage spikes caused by lightning and electrostatic discharge. In consumer electronics, it is commonly used to protect home theater systems, cameras, audio/video equipment, and other home entertainment devices from ESD. In industrial applications, it is used to protect industrial control systems from voltage transients. Finally, in telecommunications, it is used to protect telecommunications equipment from ESD.

The MP5KE20CA has a unique working mechanism. When a voltage transient occurs, the device begins to capture the energy stored in the transient and divert it away. This process starts with a bidirectional diode that acts like a capacitor and stores energy from the transient. This stored energy is then dumped into a special low-impedance path where it is dissipated as heat. This allows the device to provide protection against high-energy transients that may exceed its peak pulse current rating.

As an added benefit, the device also features a low capacitance design. This allows it to respond to transients at a lower voltage and significantly reduce the amount of energy it needs to dissipate. This helps reduce the amount of heat generated and improves reliability.

The MP5KE20CA is an ideal choice for applications that require protection from high-energy transients such as lightning and electrostatic discharge (ESD). It has a 5.0 ampere peak pulse current rating and a low-capacitance design that helps reduce the energy needed to dissipate. It is also usable in a variety of applications, including automotive, consumer electronics, industrial and telecommunications.
