SP0502BAHTG

UMW · ESD And Surge Protection (TVS/ESD) · SOT-23

SP0502BAHTG from UMW, 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 Pin 1 passive Pin 1 is one of the two protected datalines, paired with Pin 2 against Pin 3 in the 120 pF junction capacitance test (VR=0V, f=1MHz); the datasheet does not name its function or give a pin-specific voltage limit.
2 Pin 2 passive Pin 2 is the second protected dataline, paired with Pin 1 against Pin 3 in the junction capacitance test (VR=0V, f=1MHz); the datasheet does not name its function or give a pin-specific voltage limit.
3 Pin 3 passive Pin 3 is the common reference pin for the Pin 1 and Pin 2 measurements in the junction capacitance test; the datasheet does not name it as GND or state its own limits.

CAD (KiCad official)

  • Symbol: SP0502BAHTG
  • Footprint: Package_TO_SOT_SMD:SOT-23
  • 3D model: SOT-23 (KiCad packages3D, STEP)
  • 3D model files: sp0502bahtg-etched.step / sp0502bahtg-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); sp0502bahtg.step / sp0502bahtg.glb are the bare package body.

Provenance

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

  • Datasheet: UMW datasheet (7 pp, sha256 1bf01ab861003748, retrieved 2026-10-20, tier: lcsc)
  • Extractor: ds2sf (Claude). Every pin and dimension is cited to a datasheet page; it refuses to fabricate.
