BC817-16-6AF
FOSAN · Bipolar (BJT) · SOT-23
BC817-16-6AF from FOSAN, 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 | B | input | Base of the NPN transistor; emitter-base voltage is limited to 5 V (VEBO) and base-emitter on voltage is 1.2 V max at VCE=1 V, IC=500 mA. |
| 2 | E | passive | Emitter of the NPN transistor; total power dissipation is 300 mW at Ta=25 C and junction temperature is -55 to +150 C. |
| 3 | C | passive | Collector of the NPN transistor; rated for IC 500 mA, with VCEO 45 V and VCBO 50 V for BC817-16-6AF. |
