LBZX84C20LT1G

LRC · Zener Diodes · SOT-23

LBZX84C20LT1G from LRC, in a SOT-23. 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 Anode passive Anode of the zener diode, per the datasheet pinout (1-Anode, 2-No Connection, 3-Cathode); the LBZX84C20LT1G has a nominal VZ of 20 V (18.8 V min to 21.2 V max at IZT1 = 5 mA).
2 NC unconnected No internal connection; the datasheet pinout lists this pin as No Connection.
3 Cathode passive Cathode of the zener diode; device total dissipation is 225 mW on an FR-5 board or 300 mW on an alumina substrate at TA = 25°C.
