TC7SZ02FE from TOSHIBA LJ CT, in a SOT-553. Pinout and pin descriptions extracted from the manufacturer datasheet by ds2sf; symbol, footprint, and 3D from KiCad-official CAD.
Pinout
| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | INB | input | CMOS logic input B to the 2-input NOR gate. Threshold VIH >= 0.7VCC, VIL <= 0.3VCC (VCC 2.3-5.5 V). 5.5 V tolerant regardless of VCC. |
| 2 | INA | input | CMOS logic input A to the 2-input NOR gate. Threshold VIH >= 0.7VCC, VIL <= 0.3VCC (VCC 2.3-5.5 V). 5.5 V tolerant regardless of VCC. |
| 3 | GND | power_in | Ground reference (0 V). Connect to system ground. |
| 4 | OUTY | output | NOR gate output Y = NOT(A OR B). Push-pull CMOS output with ±24 mA (min) drive at VCC = 3.0 V. Features 5.5 V power-down protection (safe with VCC = 0 V and up to 5.5 V on the output). |
| 5 | VCC | power_in | Positive supply, 1.65 V to 5.5 V operating range. Decouple locally with a 0.1 uF ceramic capacitor to GND. |

Two STEP files. Same geometry, different body top:
| File | Size | Use it when |
|---|---|---|
tc7sz02fe.step |
380 KB | You want the bare part, or you mark your own boards. |

1.6 MB | You want the part with TC7SZ02FE already on it. |
The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 354 faces against 47 in the bare model. It survives export, section views, and rendering in any CAD tool, and it drops straight into KiCad or Fusion with no extra setup.
