SZMMBZ5241BLT1G

onsemi · Zener Diodes · SOT-23

SZMMBZ5241BLT1G from onsemi, 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 (SOT-23 Style 8); VF is 0.9 V max at IF = 10 mA.
2 NC unconnected No connection (SOT-23 Style 8 pin 2).
3 Cathode passive Cathode of the Zener diode, marked by the polarity band; the 11 V nominal Zener voltage (10.4 V min to 11.55 V max) is specified at IZT = 20 mA.
