KEC Semicon · Bipolar (BJT) · SOT-89
KTA1663-Y-RTF from KEC Semicon, in a SOT-89. 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 | BASE | passive | Base terminal of the PNP transistor; the base current IB is rated at -0.3 A maximum. |
| 2 | COLLECTOR (HEAT SINK) | passive | Collector terminal, also the heat-sink tab; collector current IC is rated at -1.5 A, and collector power dissipation PC* is 1 W when mounted on a ceramic substrate (250 mm² x 0.8t). |
| 3 | EMITTER | passive | Emitter terminal of the PNP transistor; the emitter-base voltage VEBO is rated at -5 V. |
