LMSZ5263BT1G

LRC · Zener Diodes · SOD-123

LMSZ5263BT1G 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, identified by the polarity band on the package; Zener regulation for the LMSZ5263BT1G (nominal VZ 56 V, range 53.2 V to 58.8 V at IZT 2.2 mA) is specified for this device.
2 Anode passive Anode terminal; the datasheet gives a maximum forward voltage VF of 0.9 V at IF = 10 mA for this device family.
