# C2001L011

**ALJ** · Bipolar (BJT) · TO-92

C2001L011 from ALJ, in a TO-92. 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 | NPN transistor emitter; the datasheet's emitter-base ratings are VEBO 5 V and emitter-base breakdown V(BR)EBO of 5 V minimum at IE = 100 µA. |
| 2 | Collector | passive | NPN transistor collector; the datasheet rates collector current IC at 0.7 A, collector-emitter voltage VCEO at 25 V, and collector power dissipation PC at 600 mW. |
| 3 | Base | passive | NPN transistor base; the datasheet tests VCE(sat) and VBE(sat) with IC = 700 mA and IB = 70 mA. |
