PANJIT International · Zener Diodes · SOT-23
MMBZ5242B_R1_00001 from PANJIT International, 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 | A | passive | Zener anode, the lower-left lead of the SOT-23 single-diode symbol (410 mW rating, Vz 12 V nominal for MMBZ5242B). |
| 2 | NC | unconnected | No internal connection; the lower-right lead of the single-diode SOT-23 symbol is not wired to the diode. |
| 3 | K | passive | Zener cathode, the top single lead of the SOT-23 package, connected to the cathode bar of the diode symbol. |
