Pin Number Pin Name Function Pin 1 Cathode Connected to the more positive side of the circuit, where voltage suppression happens. Pin 2 Anode Connected to the lower or negative side of the circuit to provide the path for ESD energy absorption.2. Circuit Principle:
The ESD5Z5.0T1G is a transient voltage suppressor designed for clamping ESD voltage transients to safe levels. When an electrostatic discharge (ESD) occurs, the diode will momentarily conduct to absorb the energy from the pulse. The cathode is connected to the protected side of the circuit, while the anode is grounded. This results in a rapid response to ESD events, with the diode clamping the voltage to a safe threshold.
The specific function of the part is to limit the peak voltage of an ESD event to below the clamping voltage rating (in this case, typically around 5V), protecting sensitive components downstream from the transient.
