SZBZX84B7V5LT1G from onsemi, in a SOT-23. 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 | Anode | passive | Anode of the Zener diode; the Zener operates in reverse breakdown with the cathode (pin 3) positive relative to this pin, and forward voltage is 0.90 V max at IF = 10 mA. |
| 2 | NC | unconnected | No connection internally (STYLE 8, pin 2 is No Connection). |
| 3 | Cathode | passive | Cathode of the Zener diode, indicated by the polarity band; for the 7.5 V B-grade part VZ is 7.35 V min to 7.65 V max at IZT = 5 mA. |
