YONGYUTAI · Bipolar (BJT) · SOT-89
FCX458 from YONGYUTAI, 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 terminal of the NPN transistor; base current is rated up to 200 mA and emitter-base voltage up to 5 V. |
| 2 | C | passive | Collector terminal; VCEO and VCBO are rated at 400 V, with continuous collector current of 225 mA and peak pulse current of 1 A. |
| 3 | E | passive | Emitter terminal of the NPN transistor, the common reference for the collector-emitter and emitter-base voltage ratings. |
