A Transient Voltage Suppressor (TVS) diode is a three-terminal, unidirectional, unipolar electronic device for suppressing transient overvoltage. The 3KP90CA-B is a type of TVS Diode that is used to protect sensitive electronics from voltage spikes.ApplicationsThe 3KP90CA-B is designed to protect electronic devices against transients in a range of applications including computer systems, automotive electronics, telecommunications and industrial equipment. It can be used on circuits with a maximum voltage of 18V and a maximum surge current of 9A. The 3KP90CA-B is designed to protect circuits from voltage transients such as electrostatic discharge (ESD) and load dump events.Working PrincipleThe 3KP90CA-B utilizes a reverse polarity breakdown structure to significantly reduce the peak voltage of transients. When an overvoltage transient is applied, the 3KP90CA-B’s structure is activated and allows a large amount of current to flow between the anode and the cathode in a very short time. The current flow reduces the peak voltage of the transient and thus suppresses its effects.The 3KP90CA-B is designed to enter the protection state very quickly, with a response time of only 10ns. It is also capable of sustaining a high number of transient events, with its surge capability rated up to 400W.ConclusionThe 3KP90CA-B is a Transient Voltage Suppressor (TVS) diode designed to protect electronic devices from surge voltages. It features a reverse polarity breakdown structure to quickly and efficiently reduce the peak voltage of transients, and can sustain surge events of up to 400W. It has a wide range of applications including computer systems, automotive electronics, telecommunications and industrial equipment.
