LMSZ5236BT1G 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, marked by the polarity band on the package; for the LMSZ5236BT1G the nominal Zener voltage is 7.5 V (min 7.13 V, max 7.88 V) at IZT = 20 mA, with 500 mW total power dissipation rating on FR-5 board. |
| 2 | Anode | passive | Anode, the opposite terminal to the cathode band; the device junction and storage temperature range is -55 °C to +150 °C. |
