KTA1659A-Y-U
KEC Semicon · Bipolar Transistors - BJT · TO-220F-3
KTA1659A-Y-U from KEC Semicon, in a TO-220F-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 | BASE | input | Base terminal of the PNP transistor; base current IB is rated at -0.15 A max and VEBO at -5 V. |
| 2 | COLLECTOR | passive | Collector terminal; IC max -1.5 A and VCEO of -160 V (KTA1659) or -180 V (KTA1659A). |
| 3 | EMITTER | passive | Emitter terminal of the PNP transistor; emitter-base voltage VEBO is limited to -5 V. |
