KSC2690AYSTU
onsemi · Audio Amplifiers · TO-126-3
KSC2690AYSTU from onsemi, in a TO-126-3. 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 | Emitter | passive | Emitter terminal of the NPN transistor; the datasheet lists the emitter-base voltage rating as 5 V (VEBO). |
| 2 | Collector | passive | Collector terminal of the NPN transistor; the datasheet rates collector current at 1.2 A DC and 2.5 A pulsed, with collector-base and collector-emitter voltage of 120 V (KSC2690) or 160 V (KSC2690A). |
| 3 | Base | passive | Base terminal of the NPN transistor; the datasheet rates base current at 0.3 A DC. |
