6. Installation and Circuit Design Considerations:\

When installing the P6KE200A TVS, proper circuit design and layout are essential to ensure effective transient protection. Here are some considerations:

Placement: The TVS diode should be located as close as possible to the input power or signal line it is protecting. This minimizes the length of the trace and reduces the potential for inductive effects.

Grounding: Establishing a low-impedance connection to the ground is crucial for the TVS diode to effectively divert the excess voltage. Care should be taken to ensure a solid grounding scheme.

Coordinated Protection: In some cases, a combination of TVS diodes with different breakdown voltages may be required to cover a wider range of transient events. This coordinated protection helps provide comprehensive safeguarding for the circuit.
