2SD669U
CBI · Bipolar (BJT) · SOT-89
2SD669U from CBI, 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; emitter-base voltage is limited to 5 V and the collector-base breakdown is 180 V minimum. |
| 2 | C | passive | Collector of the NPN transistor; VCEO is 160 V, VCBO is 180 V, and continuous collector current is 1.5 A. |
| 3 | E | passive | Emitter of the NPN transistor, the common terminal for the 1.5 A continuous collector current. |
