onsemi · Zener Diodes · SOT-23
MMBZ5246BLT1G 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 terminal of the Zener diode; per the SOT-23 Style 8 pinout the datasheet gives pin 1 as ANODE. |
| 2 | NC | unconnected | No connection; the datasheet pinout ("1-Anode, 2-No Connection, 3-Cathode") leaves this pin unconnected. |
| 3 | Cathode | passive | Cathode terminal of the Zener diode, indicated by the polarity band on the package; for MMBZ5246BLT1G the nominal Zener voltage is 16 V (15.20 V min to 16.80 V max at IZT = 7.8 mA). |
