ESD3Z3V3 from CBI, in a SOD-323. 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 ESD3Z3V3 TVS diode; the datasheet gives no separate electrical limit for this pin beyond the device ratings (reverse stand-off 3.3 V, peak pulse power 350 W at 8/20 µs). |
| 2 | Anode | passive | Anode terminal of the ESD3Z3V3 TVS diode; the datasheet gives no separate electrical limit for this pin beyond the device ratings (reverse stand-off 3.3 V, peak pulse power 350 W at 8/20 µs). |
