S-LBZT52C27T1G

LRC · Zener Diodes · SOD-123

S-LBZT52C27T1G 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 package. The datasheet gives the total device power dissipation as 500 mW.
2 ANODE passive Anode terminal of the zener diode, opposite the cathode polarity band on the SOD-123 package.
