SMMBT5088LT1G from onsemi, in a SOT-23-3. Pinout and pin descriptions extracted from the manufacturer datasheet by ds2sf; symbol, footprint, and 3D from KiCad-official CAD.
Pinout
| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | B | input | Base of the NPN transistor. Control terminal that modulates collector current; VEBO max = 4.5 Vdc, VBE(sat) <= 0.8 Vdc at IC = 10 mA, IB = 1.0 mA. |
| 2 | E | passive | Emitter of the NPN transistor. Common return terminal; typically tied to ground or a bias network. VEBO max = 4.5 Vdc. |
| 3 | C | passive | Collector of the NPN transistor. Output terminal; VCEO max = 30 Vdc, VCBO max = 35 Vdc, IC(continuous) = 50 mAdc, VCE(sat) <= 0.5 Vdc at IC = 10 mA. |
