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 ℃.
