BZT52-B47_R1_00001 from PANJIT International, in a SOD-123. 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 Zener diode, marked by the polarity diagram as pin 1; the datasheet gives no pin-specific electrical limits, so the device ratings apply (maximum power dissipation 410 mW, operating junction and storage temperature -55 to +150 °C). |
| 2 | Anode | passive | Anode terminal of the Zener diode, marked by the polarity diagram as pin 2; the datasheet gives no pin-specific electrical limits, so the device ratings apply (maximum power dissipation 410 mW, operating junction and storage temperature -55 to +150 °C). |
