DESD5V0U1BA-7

Diodes Incorporated · TVS · SOD-323

DESD5V0U1BA-7 from Diodes Incorporated, in a SOD-323. 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 PIN1 passive One terminal of the single bidirectional ESD channel, which provides ±10 kV contact protection per IEC 61000-4-2 and has a 5 V reverse standoff voltage (VRWM).
2 PIN2 passive The other terminal of the single bidirectional ESD channel, with the same ±10 kV IEC 61000-4-2 contact protection and 5 V reverse standoff voltage (VRWM) as pin 1.

CAD (KiCad official)

  • Symbol: DESD5V0U1BA-7
  • Footprint: Diode_SMD:D_SOD-323
  • 3D model: SOD-323 (KiCad packages3D, STEP)
  • 3D model files: desd5v0u1ba-7-etched.step / desd5v0u1ba-7-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); desd5v0u1ba-7.step / desd5v0u1ba-7.glb are the bare package body.

Provenance

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

  • Datasheet: Diodes Incorporated datasheet (5 pp, sha256 d957d934ea001fdd, retrieved 2026-11-04, tier: manufacturer)
  • Extractor: parts-factory 2.0.0 / extract_pins 0.3, primary claude-haiku-5-5 (text), consensus claude-sonnet-5-5 (agreed), guards: pin_guards 0.1: passed. Pins are checked against the footprint pad set and their cited datasheet pages before publish.
  • CAD: KiCad official libraries (CC-BY-SA 4.0).
