MX5KP64AE3

TVS-diodes, or Transient Voltage Suppressors (TVS), are high terminal voltage diodes designed to limit voltage transients or pulses caused by lightning, electrostatic discharge (ESD) or other temporary voltage overloads. The MX5KP64AE3 is a commonly used TVS diode for protecting sensitive electronic components from voltage surges and other transient voltage overloads.

Applications

The MX5KP64AE3 is a surface mount, uni-directional diode series designed for industrial and commercial level surge protection, and is especially useful in suppressing ESD, electrical transients and grounding fault protection in devices such as power supplies, telecommunication equipment, automotive applications and most other applications that require transient voltage protection.

This diode series can also be used for protection of equipment printed circuit boards and the components that comprise them from lightning-induced high voltage transients. Due to its small size and low profile design, the MX5KP64AE3 can be used in applications with limited space. Furthermore, its dual-function TVS and avalanche diode make it highly effective against overvoltage conditions.

Working Principle

The MX5KP64AE3 operates by absorbing transient pulses up to 30A (8/20 μs surge pulse). This is achieved through its high energy dispersing silicon die construction, which relies on the trend for surge pulses to disperse through the entire device. This high current capacity means that during a surge, energy is absorbed into the device, effectively “clamping” the output voltage below the rated breakdown voltage. This is done through a redirection of the current from the protected equipment and the routing ground potential rise.

The combination of large ESD and surge voltage withstand ratings make the MX5KP64AE3 suitable for use in a variety of applications from consumer electronics to industrial/telecommunication applications. Furthermore its extremely low leakage current (< 0.05μA) ensures its uncompromised performance when subjected to conditions with limited temperature variations.

Conclusion

The MX5KP64AE3 is a high-performance transient voltage suppressor diode that offers superior protection for sensitive equipment and devices against most transient voltage events. The diode is able to withstand high energy transients up to 30A (8/20 μs surge pulse), and also provides an extremely low leakage current in extreme temperature conditions. This makes it the ideal choice for most lightning, ESD, and other transient voltage protection needs.
