CH93TB

COSEMITECH · Magnetic Sensors · TO-92S

CH93TB from COSEMITECH, in a TO-92S. 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 VDD power_in Supply voltage pin; the datasheet states an operating range of 3.3 V to 30 V and an absolute maximum supply voltage of 40 V.
2 GND power_in Ground pin.
3 OUT output Open collector output pin; absolute maximum output voltage is 40 V and absolute maximum output current is 30 mA.

CAD (KiCad official)

  • Symbol: CH93TB
  • Footprint: Package_TO_SOT_THT:TO-92_Inline
  • 3D model: TO-92S (KiCad packages3D, STEP)
  • 3D model files: ch93tb-etched.step / ch93tb-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); ch93tb.step / ch93tb.glb are the bare package body.

Provenance

Data extracted from the manufacturer datasheet, not a distributor listing:
