2SAR523MT2L

ROHM Semicon · Bipolar (BJT) · SOT-723

2SAR523MT2L from ROHM Semicon, in a SOT-723. 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; emitter-base voltage VEBO is limited to -5 V.
2 Emitter passive Emitter terminal of the PNP transistor; collector current IC is rated -100 mA (ICP -200 mA at Pw=10 ms single pulse).
3 Collector passive Collector terminal of the PNP transistor; VCEO and VCBO are both rated -50 V.

CAD (KiCad official)

  • Symbol: 2SAR523MT2L
  • Footprint: Package_TO_SOT_SMD:SOT-723
  • 3D model: SOT-723, generated from the KiCad footprint (body from the F.Fab outline, terminals on the pads, 0.5 mm nominal SOT-723 height). Neither the vendor nor KiCad ships a 3D model for this package, so the dimensions are nominal, not the manufacturer's CAD (STEP)
  • 3D model files: 2sar523mt2l-etched.step / 2sar523mt2l-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); 2sar523mt2l.step / 2sar523mt2l.glb are the bare package body.
