SMAJ85C is a special type of Transient Voltage Suppressor (TVS) diode known as a bidirectional diode because it provides effective over-voltage protection for both positive and negative line directions. This type of diode can be used in applications where an increased level of protection is required against unexpected power surges.

The SMAJ85C is a single-line unidirectional device that consists of two back-to-back Zener diodes with an avalanche diode in between. When the voltage on the power line exceeds the threshold Voltage, the Zener diode will trigger the avalanche diode and the current will be diverted away from the system. This makes the SMAJ85C highly effective for providing protection against over-voltage and transients.

The SMAJ85C also has a low dynamic impedance, which means that it will not create too much of a current draw on the system. It is also suitable for high-speed applications. In addition, the device is also suitable for a variety of automotive applications such as DC motors, actuators, and electronic control units, to name a few.

In terms of its working principle, the SMAJ85C senses the voltage on the power line. When the voltage exceeds the threshold voltage, it triggers the avalanche diode and the current is diverted away from the system. This helps protect the system from any type of unexpected power surges and also prevents current overload in the system.

The SMAJ85C is also known for its ability to withstand high shock and vibration which makes it ideal for use in harsh environments. It is also suitable for high power handling as its maximum peak pulse power capability is rated at 5 kW. In addition, the SMAJ85C can be used in applications requiring high-speed switching.

Overall, the SMAJ85C is an invaluable tool when it comes to supplying over-voltage protection for sensitive electronic components. Its ability to handle high mechanic shock and vibration make it suitable even for the harshest environments. Moreover, its low dynamic impedance and high power handling make it ideal for high-speed applications.
