**CBI** · ESD And Surge Protection (TVS/ESD) · SOD-323

ESD3Z7V0 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 of the unidirectional TVS diode; ESD3Z7V0 has 7 V max reverse stand-off voltage (VRWM), 7.5 V min breakdown voltage at 1 mA and 22.7 V max clamping voltage at 8.8 A (8/20 µs). |
| 2 | Anode | passive | Anode of the TVS diode, normally tied to ground; device withstands 30 kV ESD (IEC61000-4-2) and 350 W peak pulse power (8/20 µs). |
