2STR2230

STMicroelectronics · Bipolar (BJT) · SOT-23

2STR2230 from STMicroelectronics, in a SOT-23. Pinout and pin descriptions extracted from the manufacturer datasheet by ds2sf; symbol, footprint, and 3D from KiCad-official CAD.

Pinout

Pin Name Type Function
1 B input Base terminal of the PNP BJT. Drive with negative base current relative to emitter to turn the device on (IB = -100 mA typical for IC = -1 A). VEBO absolute max = -5 V.
2 E passive Emitter terminal of the PNP BJT. Typically tied to the higher-potential supply rail (e.g. VCC) in low-side PNP switch topologies. VBE(sat) around -0.9 V typical at IC = -1 A.
3 C passive Collector terminal of the PNP BJT. Handles the load current up to IC = -1.5 A DC (-3 A peak, tP < 5 ms). VCEO breakdown = -30 V, VCE(sat) = -0.25 V typical at IC = -1 A, IB = -100 mA.
