This component is also used in automotive systems for protecting sensitive ECU circuits from high voltage transients generated in the engine bay. It is widely used in high speed data interface and display circuits for over-voltage protection, as the fast response time of the diode is capable of reacting to sharp transients in voltage.

The working principle of this diode can be explained by the following: When a voltage transient occurs, the diode will quickly activate and divert the current away from the sensitive components on the circuit. This is possible due to the low capacitance formed between the diode and the substrate, allowing it to handle high surge current levels. Upon the cessation of the transient, the diode automatically returns to its off-state. Moreover, the thermal characteristics of the diode ensure that it is able to maintain its integrity over long-term use.

Along with the fast response time, the low let-through voltage of the SMAJ110CAHE3/5A makes it safer for electronic components. This component provides superior reliability and robustness with its low power loss and low junction temperature. In addition, its lead-free construction makes this component RoHS compliant.
