Additional Details:

The BZX84C4V3CA has a reverse standoff voltage of 4.3V. It is designed to quickly clamp transient voltages to a safe level, protecting downstream components. The low clamping voltage ensures that the voltage seen by the protected components does not exceed their maximum ratings during a transient event. The fast response time allows the diode to react quickly to transient events, minimizing the voltage overshoot. This TVS diode is commonly used in portable electronics, communication equipment, and automotive applications where ESD protection is critical. The small SOT-23 package allows for easy surface mounting on PCBs.
