The component you mentioned, "ESD5Z3.3T1G", is a TVS diode (Transient Voltage Suppressor) manufactured by ON Semiconductor. TVS diodes like this one are used for protecting electronic circuits from electrostatic discharge (ESD) and transient voltage spikes.
Packaging:
The ESD5Z3.3T1G comes in a SOD-323 package. This is a small, surface-mount package used for components that need to have a compact form factor while maintaining reliability.
Pin Function Specifications:
Since the SOD-323 package for the ESD5Z3.3T1G diode has only two pins, the pin function specification for each pin is as follows:
Pin Number Pin Name Function Description 1 Cathode The cathode (negative) side of the diode. This pin connects to the grounded or lower potential side of the circuit. The cathode is typically marked with a stripe on the body of the diode. 2 Anode The anode (positive) side of the diode. This pin connects to the higher potential side of the circuit.Circuit Principle:
The ESD5Z3.3T1G diode operates by clamping the voltage across its pins to a safe level when there is a voltage surge or electrostatic discharge (ESD). When a transient voltage exceeds a certain threshold (typically 3.3V for this component), the diode will begin to conduct and divert the excess voltage to ground, thus protecting sensitive electronic components from damage.
