NSVMMBT5550LT1G from onsemi, in a SOT-23. 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; forward-bias base-emitter junction to turn the device on. VEBO breakdown = 6.0 V; VBE(sat) up to 1.0 V at IC = 10 mA / IB = 1 mA. |
| 2 | E | passive | Emitter of the NPN transistor. Reference terminal for base drive; current path for IC + IB back to circuit common. |
| 3 | C | passive | Collector of the NPN transistor. High-voltage terminal; VCEO = 140 V, VCBO = 160 V, IC(continuous) = 600 mA. VCE(sat) up to 0.15 V at IC = 10 mA. |
