Changjing · Bipolar (BJT) · TO-252-2L

2SD1758 from Changjing, in a TO-252-2L. 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 pin-specific limit, and the device emitter-base voltage VEBO is 5 V.
2 COLLECTOR passive Collector terminal of the NPN transistor, rated VCBO 40 V, VCEO 32 V, continuous collector current IC 2 A, and collector dissipation PC 1.2 W.
3 EMITTER passive Emitter terminal of the NPN transistor; the datasheet gives no pin-specific limit, and the device emitter-base voltage VEBO is 5 V.
