2SD874A

Shikues · Bipolar (BJT) · SOT-89

2SD874A from Shikues, 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 passive Base terminal of the NPN transistor; the datasheet gives a minimum emitter-base breakdown voltage V(BR)EBO of 5 V at IE=10uA, IC=0, and VEBO is listed in the maximum ratings table.
2 C passive Collector terminal; the datasheet gives minimum breakdown voltages of 50 V for V(BR)CBO at IC=10uA, IE=0 and 40 V for V(BR)CEO at IC=2mA, IB=0, with DC collector current IC and power dissipation PC rated in the maximum ratings table.
3 E passive Emitter terminal, the reference for the base-emitter and collector-emitter specifications, with the emitter-base limit VEBO given in the maximum ratings table.
