2SD1898-R

Slkor SLKORMICRO Elec · Bipolar (BJT) · SOT-89

2SD1898-R from Slkor SLKORMICRO Elec, 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 Base passive Base terminal; the datasheet gives VEBO = 5 V and VBE(sat) = 1.2 V at IC = 500 mA, IB = 50 mA.
2 Collector passive Collector terminal; the datasheet rates VCBO = 120 V, VCEO = 80 V, continuous IC = 1 A and pulse ICP = 2 A.
3 Emitter passive Emitter terminal; the datasheet gives emitter-base breakdown VEBO = 5 V (IE = 100 uA, IC = 0).
