LMBTA05LT1G from LRC, in a SOT-23. 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 transistor; the datasheet specifies emitter-base breakdown voltage V(BR)EBO of 4.0 V minimum at I_E = 100 µA. |
| 2 | EMITTER | passive | Emitter terminal of the transistor; the device is rated for 500 mA maximum continuous collector current. |
| 3 | COLLECTOR | passive | Collector terminal of the transistor; the LMBTA05 collector-emitter breakdown voltage V(BR)CEO is 60 V minimum and collector-base voltage V_CBO is 60 V. |
