2SA1037-R

Yangzhou Yangjie Elec Tech · Bipolar (BJT) · SOT-23

2SA1037-R from Yangzhou Yangjie Elec Tech, in a SOT-23. 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; the package drawing places B at pin 1, with VEBO of -6 V maximum and a DC current gain hFE of 120 to 560 at VCE=-6V, IC=-1mA (rank R: 180-390).
2 E passive Emitter; the package drawing places E at pin 2, with VEBO of -6 V maximum.
3 C passive Collector; the package drawing places C at pin 3, with VCBO of -60 V, VCEO of -50 V and IC of -0.15 A maximum.
