CAD (KiCad official)

  • Symbol: THVD1451DRBT
  • Footprint: Package_SON:WSON-8-1EP_3x3mm_P0.5mm_EP1.6x2.0mm
  • 3D model: SON-8-EP(3x3) (KiCad packages3D, STEP)
  • 3D model files: thvd1451drbt-etched.step / thvd1451drbt-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); thvd1451drbt.step / thvd1451drbt.glb are the bare package body.

Provenance

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

  • Datasheet: Texas Instruments datasheet (53 pp, sha256 c4b3b0da87c870dd, retrieved 2026-10-03, tier: lcsc)
  • Datasheet language: Chinese. Pin names, descriptions, and specs on this page were extracted and translated to English by ds2sf; the linked PDF is the manufacturer original.
  • Extractor: parts-factory 2.0.0 / extract_pins 0.3, primary claude-haiku-4-5-20251001 (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.
