Working Principle
The SM8S28AHE3_A/I is designed to protect sensitive electronic equipment from damaging transient voltage spikes. It works by clamping the voltage at a predetermined level, which is usually much lower than the breakdown voltage of the protected components. The device consists of two diodes connected in anti-parallel which are then connected to the circuit rails. This ensures that a voltage overshoot on either the positive or negative rail is clamped and diverted around the circuit, protecting the protected components.
When the device operates, current from the transient voltage spike is diverted around the circuit while the peak voltage level is held at a specified voltage level. This ensures that the peak current values do not exceed the junction breakdown of the components in the circuit and prevents the damage that transient voltage spikes may cause. Furthermore, the device is able to protect against multiple transient events, allowing the device to handle multiple transient events without having to replace the diode.
Conclusion
The SM8S28AHE3_A/I is a high performance unidirectional ESD diode designed for use in industrial, automotive, military and telecommunications applications. It can protect sensitive electronic components from transient voltage spikes, ensuring the reliability and safety of the protected components.
