Changjing · Bipolar (BJT) · TO-252-2L
MJD3055 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 | NPN transistor base terminal; the datasheet gives no separate base-current rating, and the emitter-base voltage limit VEBO is 5 V. |
| 2 | COLLECTOR | passive | NPN transistor collector terminal; maximum ratings are VCBO 70 V, VCEO 60 V, continuous IC 10 A, and PC 1.25 W at Ta=25℃. |
| 3 | EMITTER | passive | NPN transistor emitter terminal; the datasheet lists the emitter-base voltage rating VEBO as 5 V. |
