3KP190A-B

TVS (transient voltage suppression) diodes are special protection devices designed to safeguard electronics from destructive voltage spikes. The 3KP190A-B is a 3-line unidirectional transient voltage suppressor (TVS) diode which is designed for protecting high-performance electronic equipment against transients caused by lightning and other electrostatic discharge-related phenomena.

The 3KP190A-B is notable due to its superior electrical ratings over that of traditional silicon TVS diodes, as well as its fast response time. It is an ideal choice for use in a variety of applications including high-voltage/high-speed data/telecommunication equipment, LAN/computers, automotive, motor control, consumer electronics, digital display, and other sensitive electronic equipment.

The 3KP190A-B is designed to absorb transient energy quickly with minimal dissipation. It has a maximum clamping voltage of 190 volts at Ipp of 200A, and a max. peak pulse current of 500A. The 3KP190A-B is packaged in an industry-standard SOD-123 surface-mount package and can be mounted on a variety of surfaces, making it suitable for broad deployment across a wide range of products.

In terms of working principle, this type of diode is comprised of a special semiconductor material which is designed to conduct current until a certain voltage level is reached. It works by allowing regular current to pass through it while limiting and controlling the voltage levels it allows. When the voltage reaches a specific level, the diode is triggered, establishing a low-resistance path for the surge of current to be diverted away from sensitive electronic components.

The 3KP190A-B TVS diode can be used as a circuit protector to guard against high-energy transients. It works by providing a virtual short circuit between the power line and the ground line when the device is subjected to a certain voltage or current level. This helps protect sensitive circuitry within the device from destructive voltage ratings or current variations due to lightning strikes or electrostatic discharges.

The 3KP190A-B TVS diode is a versatile electronic protection device that can provide robust protection against electrical transients in a variety of applications, from industrial electronics to consumer applications. It is easy to deploy within a system and provides excellent electrical ratings to ensure safe operation.
