The MP5KE85CA series are surge suppressor diodes, that are constructed as a combination of avalanche diode and transient-voltage-suppressing (TVS) diode, and is designed to protect sensitive electronic circuits from high-voltage transients. These surge suppressor diodes, also known as Transient Voltage Suppressors (TVSs), provide protection from transients induced by lightning and other unwanted voltage spikes.

The MP5KE85CA series are two-lead zener diodes with a high-wavelength package design that offers excellent protection from voltages up to 850 V. The device is specified as having a maximum reverse leak current of 1 µA at -25°C. When not conducting, it offers very low clamping voltage (typically 625 V) and excellent transient protection between -4 V and 850 V. This series of TVS diodes feature low dynamic resistance, meaning it provides highly effective protection from high-voltage transients.

The MP5KE85CA application fields are mostly industrial and automotive applications, such as AC/DC adapter protection, automotive applications, printer and copiers, consumer audio/video protection, data/telephone line surge protection etc. And their working principle is very simple, when input voltage exceeds a certain value, the avalanche diode in this device will open, conduct the high-voltage current and clamp down the voltage. Its TVS diode will also activate and absorb the electricity, protecting the circuit and devices from voltage spikes.

The MP5KE85CA series of surge suppressor diodes offer excellent protection in a wide range of applications, and can be used to protect against a range of faults such as short-circuits, over-voltages, or transients. They offer both high performance and low cost, and are a great solution for protecting sensitive equipment and systems from power surges.
