The 3KP190C-B TVS – Diodes is a transient voltage suppression device often used in portable electronic devices for suppressing transients on telecommunications and data lines. This TVS diode is a highly effective method for protecting electronic circuits against electrostatic discharges, power inductive off-load, electro-magnetic interference (EMI) and voltage transients.

It is becoming increasingly well-used for applications where size and weight are critical factors, such as laptops and tablets. It is also a popular component for audio equipment, automotive, telecommunications, digital TVs, industrial control and consumer electronics products.

The technology behind the 3KP190C-B is RoHS Compliant and is based on the introduction of a reverse biased p-n junction. This creates a large electric field which clamps the voltage present before passing it on to the load. This clamped voltage is determined by the clamping voltage of the device, and ideally should be slightly higher than the anticipated voltage value so as to protect the electronics from any transient spikes that may harm it.

Essentially, this diode will limit surges, EMI spikes and power offloads from entering the device or circuit. It will stay in an off-state until the transient voltage exceeds the breakdown voltage. Once that occurs, it then begins conducting current until the transients safely dissipate, allowing the device or circuit to return to its regular operating voltage.

Most commonly, the 3KP190C-B is connected to the wire, power line or equipment as near as possible to the source of the transient. Its tiny size makes it possible to fit far more of these devices into a given space. This allows designers to protect multiple lines while also avoiding overcrowding. As a result, more efficient protection is available when the 3KP190C-B is used.

Additionally, the 3KP190C-B is a cost effective solution to surge testing. By keeping equipment protected, it eliminates the need for separate surge tests. This type of protection can also help avoid the risks of test interference due to the transient, along with eliminating failure modes due to multiple retests.

Overall, the 3KP190C-B is an ideal choice for protecting electronic components in portables, audio equipment, automotive, telecommunications, digital TVs, industrial control and consumer electronics products. Designed to offer protection from EMI noise, electromechanical transients, and power off-loads, it is a highly effective solution for protecting equipment from damage by transient voltages.
