ROHM Semicon · Bipolar Transistors - BJT · SOT-89

2SD1898T100R from ROHM Semicon, 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 of the NPN transistor; the datasheet gives IB = 50mA at IC = 500mA for VCE(sat) and a VEBO limit of 5V.
2 C passive Collector of the NPN transistor; rated VCEO 80V, VCBO 120V, IC 1A continuous and 2A pulsed (Pw=10ms).
3 E passive Emitter of the NPN transistor; VEBO maximum 5V.
