SZESD5B5.0ST5G
onsemi · ESD And Surge Protection (TVS/ESD) · SOD-523
SZESD5B5.0ST5G 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 | 1 | passive | One terminal of the bi-directional ESD protection diode, rated for a 5.0 V reverse working (stand-off) voltage; the SOD-523 outline Style 1 labels this pin CATHODE (polarity band), but the device is described as bi-directional, so polarity may not apply. |
| 2 | 2 | passive | The other terminal of the bi-directional ESD protection diode, rated for IEC 61000-4-2 contact ESD of ±30 kV; the SOD-523 outline Style 1 labels this pin ANODE. |
