S-LMSZ5267BT1G

LRC · Zener Diodes · SOD-123

S-LMSZ5267BT1G 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 is marked by the polarity band on the SOD-123 package, and the device is rated for 500 mW total power dissipation on FR-5 board at TL = 75°C.
2 Anode passive Anode is the opposite terminal of the Zener diode, with the device operating over a junction and storage temperature range of −55°C to +150°C.
