8.2.2 Detailed Design Procedure

If the TVS5800 is in place to protect the device, during a surge event the voltage rises to the breakdown of the diode at 69.8V, and then the TVS5800 turns on, shunting the surge current to ground. With the low dynamic resistance of the TVS5800, large amounts of surge current has minimal impact on the clamping voltage. The dynamic resistance of the TVS5800 is around 40mΩ, which means 25A of surge current causes a voltage raise of 25A × 40mΩ = 1V. Because the device turns on at 69.8V, this means the TPS23882 input is exposed to a maximum of 69.8V + 1V = 70.8V during surge pulses. This maintains robust protection of your circuit.

The small size of the device also improves fault protection by lowering the effect of fault current coupling onto neighboring traces. The small form factor of the TVS5800 allows the device to be placed extremely close to the input connector, lowering the length of the path fault current takes through the system compared to larger protection designs.
