3KP64A

TVS (Transient Voltage Suppressor) Diode is a class of semiconductor components that help to protect circuits from transient voltages and discharges. 3KP64A is a type of TVS diode. It is a two-terminal, unidirectional device aimed at protecting components and systems from transient over voltage (EOS) conditions.

The 3KP64A has a variety of possible applications, thanks to its ability to protect against damages to sensitive equipment in both automotive and industrial applications. Some of the most common applications include: Data communication, Mobile phone chargers, LED lighting, Automotive radar, Automotive telematics, and Automotive radio/infotainment.

The 3KP64A operates on the principle of a reverse polarity voltage spike or over voltage condition, which exceeds the maximum breakdown rating of the TVS diode, resulting in the diode being “turned on” and reducing or blocking any incoming surge to the load. This process of the diode being turned on is known as “avalanche breakdown”. When the current falls below the the threshold voltage, the diode then turns off and the circuit returns to normal.

The 3KP64A is also designed to be less susceptible to surger repetition. This is because the first avalanche effect is said to “condition” and effectively pre-charge the surface of the diode, making it less susceptible to follow-on transient peak currents. This type of diode also has an upper limit on the peak voltage before it begins to conduct, known as its Peak Pulse Power Rating (PPPR), and this is typically 2.8kV for the 3KP64A diode.

In addition, the 3KP64A has a very fast response time, which is typically one nanosecond or less, and it is capable of controlling both positive and negative surge current transients with equal efficiency. Thanks to its properties, the 3KP64A is suitable for medium power applications.

The 3KP64A is designed to provide protection from a broad range of physical and electrical hazards, and is designed to survive multiple transient voltage events. It is also able to withstand long-term exposure to over voltage conditions. As such, it is a reliable and cost effective solution for protecting sensitive electronic components and systems in a wide range of industrial and automotive applications.
