LRC · Zener Diodes · SOD-123
LBZT52C3V0T1G 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 SOD-123 body; the datasheet rates the device at 500 mW total power dissipation on an FR-5 board and a junction and storage temperature range of -55 to +150 °C. |
| 2 | ANODE | passive | Anode terminal of the Zener diode; the datasheet gives a forward voltage of 0.9 V max at IF = 10 mA. |
