SZESD9R3.3ST5G

onsemi · TVS · SOD-923

SZESD9R3.3ST5G from onsemi, in a SOD-923. 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 (polarity band) of the uni-directional ESD protection diode, connected to the protected line, with VRWM 3.3 V and leakage under 1 nA at 1 V from 0°C to 50°C.
2 ANODE passive Anode of the uni-directional ESD protection diode, normally tied to ground, which clamps IEC61000-4-2 ESD events with a maximum VC of 7.8 V at IPP = 1 A.
