LMSZ5247BT1G from LRC, 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 band on the package; the datasheet states no separate pin-level electrical limits. |
| 2 | Anode | passive | Anode terminal of the Zener diode, which connects to the cathode through the device's reverse-biased Zener breakdown; the datasheet states no separate pin-level electrical limits. |
