LMSZ5253BT1G 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 of the Zener diode, marked by the polarity band on the package; the datasheet gives the device's nominal Zener voltage as 25 V (min 23.75 V, max 26.25 V) at IZT = 9.5 mA... |
| 2 | ANODE | passive | Anode of the Zener diode, the non-banded terminal opposite the cathode, per the SOD-123 Style 1 pin assignment. |
