DTC143EKA
Foshan Blue Rocket Elec · Digital Transistors · SOT-23
DTC143EKA from Foshan Blue Rocket Elec, 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 | Base | input | Base input of the NPN digital transistor, with built-in bias resistor R1 (4.7 kΩ typical, 3.29 to 6.11 kΩ); the datasheet gives VI(off) max 0.5 V at VCC=5.0 V, VI(on) 3.0 V at VO=0.3 V and IO=20 mA, and input current II max 1.8 mA at VI=5.0 V. |
| 2 | Emitter | passive | Emitter terminal of the NPN digital transistor, the common reference for the output stage; the datasheet does not state a separate pin-level limit for this pin. |
| 3 | Collector | passive | Collector output of the NPN digital transistor, rated for output voltage VCC up to 50 V (the adjacent 30 V row is ambiguous), output current IO 100 mA maximum, and VO(on) of 0.3 V max at IO=10 mA, II=0.5 mA. |
