2SAR553P5T100

ROHM Semicon · Bipolar (BJT) · SOT-89

2SAR553P5T100 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 PNP transistor; VEBO max -6 V, IEBO max -1.0 µA at VEB = -4 V, IB = -35 mA used for VCE(sat) test.
2 C passive Collector (center lead, also the tab) of the PNP transistor; VCEO -50 V, VCBO -50 V, IC -2 A continuous, ICP -4 A pulsed.
3 E passive Emitter of the PNP transistor, connected to the most positive supply in typical high-side use.
