Working Principle

The DD171N12KKHPSA1 diode-array device consists of two power diodes in series and a parallel double diode at the end. The two power diodes in the circuit offer a low forward voltage drop of 0.4 V, for efficient voltage regulation. The double diode at the end provides extended protection from overvoltages, static discharges, and transients. The low on-state resistance of the diodes help to minimize power loss in the circuit.

In operation, when the input voltage exceeds the clamping voltage of the diode-array device, the diodes conduct and divert the excess current away from the device, thus protecting it from damage. Conversely, when the input voltage is low, the device acts as an open-circuit and does not allow current to flow. Therefore, the device helps to protect downstream components from overvoltage, static discharges, and transients.
