ESDA14V2SC5

STMicroelectronics · ESD And Surge Protection (TVS/ESD) · SOT-23-5

ESDA14V2SC5 from STMicroelectronics, in a SOT-23-5. 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 IO1 passive Protected data/transmission line input connected to a unidirectional Transil ESD protection diode that clamps positive transients to the clamping voltage VCL and negative transients to one diode drop below GND, sharing its Transil with pin 5 and referenced to the common pin 2.
2 GND power_in Common ground/return node connecting the cathodes of the two internal Transil diode pairs (channels 1-5 and 3-4), providing the reference for clamping the protected I/O lines.
3 IO2 passive Protected data/transmission line input connected to a unidirectional Transil ESD protection diode that clamps positive transients to the clamping voltage VCL and negative transients to one diode drop below GND, sharing its Transil with pin 4 and referenced to the common pin 2.
4 IO3 passive Protected data/transmission line input connected to a unidirectional Transil ESD protection diode that clamps positive transients to the clamping voltage VCL and negative transients to one diode drop below GND, sharing its Transil with pin 3 and referenced to the common pin 2.
5 IO4 passive Protected data/transmission line input connected to a unidirectional Transil ESD protection diode that clamps positive transients to the clamping voltage VCL and negative transients to one diode drop below GND, sharing its Transil with pin 1 and referenced to the common pin 2.

CAD (KiCad official)

  • Symbol: ESDA14V2SC5
  • Footprint: Package_TO_SOT_SMD:SOT-23-5
  • 3D model: SOT-23-5 (KiCad packages3D, STEP)
  • 3D model files: esda14v2sc5-etched.step / esda14v2sc5-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); esda14v2sc5.step / esda14v2sc5.glb are the bare package body.

Provenance

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

  • Datasheet: STMicroelectronics datasheet (9 pp, sha256 83535cf61c43011c, retrieved 2026-09-29, tier: lcsc)
  • Extractor: ds2sf (Claude). Every pin and dimension is cited to a datasheet page; it refuses to fabricate.
  • CAD: KiCad official libraries (CC-BY-SA 4.0).
