S-LMBT3904LT1G
LRC · Bipolar (BJT) · SOT-23
S-LMBT3904LT1G 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 NPN general-purpose transistor; the datasheet gives no separate base-pin limit, so it is governed by the device ratings (VCEO 40 V, VCBO 60 V, VEBO 6 V, continuous IC 200 mA max). |
| 2 | EMITTER | passive | Emitter terminal of the NPN transistor; the emitter-base voltage VEBO is rated at 6 V maximum, and continuous collector current IC is limited to 200 mA. |
| 3 | COLLECTOR | passive | Collector terminal of the NPN transistor; the collector-emitter voltage VCEO is rated at 40 V and collector-base voltage VCBO at 60 V maximum, with continuous collector current limited to 200 mA. |
