2SD1664

hongjiacheng · Bipolar (BJT) · SOT-89

2SD1664 from hongjiacheng, 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; the datasheet gives an emitter-base voltage rating VEBO of 5.0 V and an emitter-base cut-off current IEBO of 0.5 µA max at VEB = 4.0 V.
2 C passive Collector terminal; the datasheet limits are collector-base voltage VCBO 40 V, collector current IC 1.0 A, and collector power dissipation PC 0.5 W.
3 E passive Emitter terminal; the collector-emitter breakdown voltage V(BR)CEO is 32 V minimum at IC = 1.0 mA, IB = 0.
