LRC · Zener Diodes · SOD-123
LBZT52C51T1G 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's equivalent circuit labels pin 1 as Cathode. |
| 2 | ANODE | passive | Anode terminal of the Zener diode; the datasheet gives forward voltage VF of 0.9 V max at IF = 10 mA and a total power dissipation of 500 mW. |
