BZX84B16HE3-TP from MCC(美微科), 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 diode anode, connected to the left bottom lead in the internal structure drawing. |
| 2 | NC | unconnected | No internal connection; the right bottom lead is not wired to the die in the internal structure drawing. |
| 3 | K | passive | Zener diode cathode on the single top lead; nominal VZ 16.00 V (15.68 V to 16.32 V) at IZT = 5 mA for BZX84B16HE3. |
