MMBTRC105SS

YFW · Digital Transistors · SOT-23

MMBTRC105SS from YFW, 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 Input pin of the built-in bias network (R1 = 2.2 kΩ for MMBTRC105SS), with input voltage limits of 12 V and -5 V as absolute maximum ratings.
2 Emitter passive Common emitter of the transistor, which the datasheet labels as the common terminal of the built-in R1/R2 network (R2 = 47 kΩ for MMBTRC105SS).
3 Collector output Output pin with a maximum output voltage of 50 V and maximum output current of 100 mA (absolute maximum ratings, Ta = 25 °C).
