2SD1898T100Q

ROHM Semicon · Bipolar (BJT) · SOT-89

2SD1898T100Q 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, driven with IB = 20 mA for VCE(sat) = 0.4 V max at IC = 500 mA, with VEBO limit of 5 V.
2 C passive Collector (also the wide center tab), with VCEO of 80 V, VCBO of 120 V and IC of 1.0 A DC (2.0 A pulsed).
3 E passive Emitter of the NPN transistor, the common return for the collector and base currents, with VEBO limit of 5 V.
