2SAR542PT100

ROHM Semicon · Bipolar (BJT) · SOT-89

2SAR542PT100 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 Base input Base terminal of the PNP transistor; the datasheet gives VEBO of -6V, and VCE(sat) of -0.4V max at IC/IB = -2A/-100mA.
2 Collector passive Collector terminal (also the tab on the SOT-89 body); the datasheet gives VCBO of -30V, VCEO of -30V, IC of -5.0A DC and ICP of -10A pulsed.
3 Emitter passive Emitter terminal of the PNP transistor; the datasheet gives VEBO of -6V.
