KSC2073TU

onsemi · Bipolar (BJT) · TO-220

KSC2073TU from onsemi, in a TO-220. 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 NPN transistor; the datasheet gives no separate pin-level limit, and the device ratings apply (VEBO = 5 V, IC = 1.5 A maximum).
2 Collector passive Collector terminal of the NPN transistor, rated for VCBO = 150 V and VCEO = 150 V, with collector current IC = 1.5 A and collector dissipation PC = 25 W at TC = 25°C.
3 Emitter passive Emitter terminal of the NPN transistor, with emitter-base voltage VEBO = 5 V as the maximum rating.
