ESD5Z3.3T5G

onsemi · ESD And Surge Protection (TVS/ESD) · SOD-523

ESD5Z3.3T5G from onsemi, in a SOD-523. Pinout and pin descriptions extracted from the manufacturer datasheet (extract_pins, cross-checked by a second model); symbol, footprint, and 3D from KiCad-official CAD.

Pinout

Pin Name Type Function
1 CATHODE passive Cathode of the unidirectional ESD protection diode, identified by the polarity band; the ESD5Z3.3 working peak reverse voltage (VRWM) is 3.3 V.
2 ANODE passive Anode of the ESD protection diode, which clamps ESD and transient events on the protected line; the device is rated for ±30 kV IEC 61000-4-2 contact discharge.
