KTA1659A
Changjing · Pre-ordered transistors · TO-220F
KTA1659A from Changjing, in a TO-220F. 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; the datasheet rates the emitter-base voltage VEBO at -5 V. |
| 2 | COLLECTOR | passive | Collector terminal; the datasheet rates the collector-base voltage VCBO at -180 V and the collector current IC at -1.5 A. |
| 3 | EMITTER | passive | Emitter terminal; the datasheet gives an operation junction and storage temperature range of -55 to +150 ℃. |
