**KEC Semicon** · Bipolar (BJT) · TO-92L

KTB764-GR-AT from KEC Semicon, in a TO-92L. 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 | EMITTER | passive | Emitter terminal of the PNP transistor; the emitter-base voltage is rated VEBO -5 V, and IEBO was specified with VEB = -4 V. |
