# LMBZ5228BLT1G

**LRC** · Zener Diodes · SOT-23

LMBZ5228BLT1G from LRC, in a SOT-23. 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 | Anode | passive | Anode terminal of the Zener diode, the non-polarity-banded end of the SOT-23 package. The datasheet gives a maximum forward voltage of 0.95 V at IF = 10 mA (0.9 V max for all types in the table on page 3). |
| 2 | NC | unconnected | No internal connection; the datasheet labels this pin 'No Connection'. |
| 3 | Cathode | passive | Cathode terminal of the Zener diode, identified on the package by the polarity band; it is the regulated (Zener) terminal in the series. |

## CAD (KiCad official)

- Symbol: `LMBZ5228BLT1G`
- Footprint: `Package_TO_SOT_SMD:SOT-23`
- 3D model: SOT-23 (KiCad packages3D, STEP)
- 3D model files: `lmbz5228blt1g-etched.step` / `lmbz5228blt1g-etched.glb` carry the MPN laser-etched on the die in a toggleable `Adom.LaserEtch` group (Fusion-ready); `lmbz5228blt1g.step` / `lmbz5228blt1g.glb` are the bare package body.
