SZBZX84C15ET1G 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 datasheet gives no separate pin-specific limit, and the device is rated for 250 mW total power dissipation on FR-5 board and a junction and storage temperature range of −65 to +150 °C. |
| 2 | NO CONNECTION | unconnected | Not internally connected; the datasheet specifies this pin as No Connection for the SOT-23 Style 8 pinout. |
| 3 | CATHODE | passive | Cathode of the Zener diode, identified on the package by the polarity band; the series covers Zener breakdown voltages from 2.4 V to 75 V. |
