Transient Voltage Suppression (TVS) diodes are semiconductor devices used for electrical overstress (EOS) protection. They are also known as surge suppressors or clamping diodes. Having a high surge handling capability, they can absorb and dissipate an excessive surge energy from the circuit in which it is connected, thereby providing a protective gap. TVS diodes are one of the most commonly used components for EOS protection in many applications including automotive, industrial, communication and consumer electronics.

3KP6.5C is one type of TVS diode designed to protect low-voltage applications and sensitive electronic circuits from voltage transient and ESD. Available in ultra-low capacitance SOD-923 package, 3KP6.5C is designed to meet the stringent requirements of high-speed signal systems such as LAN, serial data, video, and other communication systems.

Application Field

3KP6.5C diode can be used to protect against low or ultra-low capacitance, low-clamping voltage surge stoppers in electronic circuits. This type of diode can protect from many types of transients including ESD (electrostatic discharge), electrical overstress (EOS) events such as card insertion, and other voltage transients. It is widely used for Automated Test Equipment (ATE), any application involving data, communication and video over twisted pair, and other low-voltage applications. It also can be used in power supply, computer monitor, television, digital camera, medical equipment and other consumer electronics.

Working Principle

3KP6.5C diode consists of a zener diode connected in series with an NPN silicon power transistor. In steady-state operation, the diode conducts the initial current spike generated by a surge. When the applied voltage exceeds the diode\'s breakdown voltage, the power transistor is activated and begins to conduct current away from the load. This pulls the load voltage down and clamps it to the breakdown voltage. This dynamic clamping
