LRC · Bipolar (BJT) · SOT-89
LBSS4350SY3T1G from LRC, in a SOT-89. 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 | B | input | Base of the NPN transistor; the datasheet gives VEBO of 6 V maximum and VCBO of 60 V maximum. |
| 2 | C | passive | Collector of the NPN transistor; the datasheet gives VCEO of 50 V, IC of 3 A and ICP of 6 A (pulse) maximum. |
| 3 | E | passive | Emitter of the NPN transistor, shown with the arrow pointing out of the device in the symbol; VEBO is 6 V maximum. |
