ESD9L3.3ST5G 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 terminal of the unidirectional ESD protection diode, identified by the polarity band on the SOD-923 package (Style 1); the device has a 3.3 V working peak reverse voltage (VRWM) and 0.5 pF typical capacitance at VR = 0 V, f = 1.0 MHz. |
| 2 | ANODE | passive | Anode terminal of the unidirectional ESD protection diode; the datasheet gives the device's IEC 61000-4-2 contact rating of ±10 kV (Table: Maximum Ratings) and 1.0 µA maximum reverse leakage at VRWM. |
