Diodes Incorporated · Zener Diodes · SOT-23-3
MMBZ5227BW-7-F from Diodes Incorporated, in a SOT-23-3. 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, shown in the page 1 device schematic at the bottom-left terminal, with forward voltage 0.9 V at IF = 10 mA. |
| 2 | NC | unconnected | No internal connection, shown in the page 1 device schematic as the bottom-right terminal with no connection to the diode. |
| 3 | K | passive | Zener cathode, shown in the page 1 device schematic at the top terminal, with VZ of 3.6 V nominal (3.42 V min to 3.78 V max) at IZT = 20 mA for the MMBZ5227BW. |
