TVS diodes are one of the few components that provide protection of automotive and consumer electronics from Electrostatic Discharge (ESD) and Transient Voltage Spikes (TVS). TVS-Diodes, also known as Transil, are elements which are designed to protect electronic components against over-voltage transients. The 5KP200-B is one of the many clamps available. It is able to provide commonly required over-voltage protection in order to protect automotive and consumer Electronic circuits from ESD and TVS.

The 5KP200-B is a unidirectional Transient Voltage Suppression Diode which can be used to protect against positive or negative transient over-voltages. It is constructed from a 5.6KV PN junction in a Zener breakdown structure.5KP200-B is mainly designed for use in automotive and consumer electronics applications. The device has a peak power dissipation of 400W at a pulse width of 10/1000 microseconds and a storage temperature range of -55 to + 150 °C. It is capable of suppressing transients up to 200A.

The working principle of 5KP200-B largely revolves around the Zener diode structure. When excess voltage is applied, the diode will break down due to the Zener breakdown, and the device will begin to conduct current. This current will be limited by the voltage dropping across the diode, thus protecting the device from any further damage. With regard to ESD and TVS protection, the 5KP200-B has an ESD breakdown voltage rating which is greater than the typical values for ESD protection.

The 5KP200-B is suitable for most general over-voltage and over-current protection on applications such as sensing circuits, logic ICs as well as other digital circuits. It features a low dynamic resistance, making it a better choice than the diodes for low-impedance circuits, as it can limit the peak current. It is however important to remember to size the chosen transient voltage suppression diode correctly, based on the application requirements, as this is critical to ensure robust protection.

In conclusion, the 5KP200-B is a TVS-Diode designed to provide protection from ESD and TVS on automotive and consumer electronic circuits. It is constructed from a 5.6KV PN junction in a Zener breakdown structure and can suppress transients up to 200A. It has a peak power dissipation of 400W and a storage temperature range of -55 to +150 °C. This makes it suitable for providing overvoltage and over-current protection on applications such as sensing circuits, logic ICs, and other digital circuits.
