SZ1SMA5934BT3G from onsemi, in a SMA. 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 (polarity band) of the zener; for this 24 V part VZ is 22.8 V min, 24 V nom and 25.2 V max at IZT = 15.6 mA, with a maximum DC zener current of 63 mA. |
| 2 | ANODE | passive | Anode of the zener; forward voltage is 1.2 V max at IF = 200 mA, and the device is rated for 1.5 W at TL = 75°C. |
