Introduction to 3KP12-B TVS Diodes
TVS diode is a type of semiconductor composed of two p-n junction diodes connected back-to-back. These devices can be used to protect electronic components and circuits from overvoltage conditions. The 3KP12-B TVS diode is a bi-directional, transient voltage suppressor designed to protect electrical equipment from destructive voltage transients, commonly known as spikes, surges and inductive switching.Application Field of 3KP12-B TVS Diode
The 3KP12-B TVS diode is designed primarily for line-to-ground protection. It is suitable for use in applications that may experience transient voltage spikes such as automotive, aerospace, medical equipment, telecommunication equipment, computer and consumer electronics.The 3KP12-B TVS diode is ideal for use in AC/DC power lines, direct current power converters, power switching circuits, and server racks. It provides surge protection for a wide variety of applications including consumer electronics, communication equipment, computer peripheral equipment, and industrial power control systems.Working Principle of 3KP12-B TVS Diode
When a high voltage spike occurs, the 3KP12-B TVS diode responds by allowing current to flow through it in either direction. As the surge reaches a certain threshold, the diode becomes forward-biased and the voltage across the junction reduces. This prevents further current flow and clamping the voltage across the diode to a safe level, thus protecting the electronic device from further damage.The 3KP12-B TVS diode is capable of providing protection for both line-to-ground and line-to-line transient voltage events. When a spike occurs in the line-to-ground configuration, the diode will pass the current in one direction and short the voltage across the diode to the ground. This will ensure that the voltage of the protected electronic device remains at a safe level. In the line-to-line configuration, the diode will short the voltage between the lines, thus protecting both lines from further damage.Conclusion
The 3KP12-B TVS diode is a bi-directional, transient voltage suppressor designed to protect electronic devices and circuits from transient voltage events such as spikes, surges and inductive switching. It is suitable for use in applications such as automotive, aerospace, medical equipment, telecommunication equipment, computer and consumer electronics. It is capable of providing protection for both line-to-ground and line-to-line events. The 3KP12-B TVS diode is a reliable and cost-effective way to protect sensitive components from voltage spikes.
