Working Principle of the P4KE75A TVS Diode

The P4KE75A TVS diode is designed to protect electronics from overvoltage transients. It is constructed with a pair of Unidirectional TVS diode chips in an hermetically sealed ceramic package. The diode chips are connected in an inverse parallel configuration , with the anode of one connected to the cathode of the other, forming a maxium clamping voltage. When an overvoltage transient occurs, the diode chip on the anode side allows current to flow. The current is then clamped and suppressed by the diode chip on the cathode side, protecting the circuit from damage caused by the overvoltage event. The P4KE75A offers excellent protection against ESD, electric surges, and any other overvoltage transients.
