NXP Semicon · Bipolar (BJT) · SOT-23-3
BFU530A from NXP Semicon, in a SOT-23-3. 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 (Table 2 lists it as 'base'); the datasheet gives no pin-specific electrical limit for this lead. |
| 2 | E | passive | Emitter terminal of the NPN transistor (Table 2 lists it as 'emitter'); the datasheet gives no pin-specific electrical limit for this lead. |
| 3 | C | passive | Collector terminal of the NPN transistor (Table 2 lists it as 'collector'); Tsp is defined at the solder point of this lead, and the datasheet gives no pin-specific electrical limit for it. |
