Storage temperature Tstg -55 150 °C printed as −55 to +150 1

CAD (KiCad official)

  • Symbol: PTZTE2520B
  • Footprint: Diode_SMD:D_SMA
  • 3D model: DO-214AC(SMA) (KiCad packages3D, STEP)
  • 3D model files: ptzte2520b-etched.step / ptzte2520b-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); ptzte2520b.step / ptzte2520b.glb are the bare package body.

Provenance

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

  • Datasheet: ROHM Semicon datasheet (5 pp, sha256 93e4958348977a87, retrieved 2026-10-13, tier: lcsc)
  • Extractor: parts-factory 2.0.0 / extract_pins, primary cathode-band convention (convention), consensus off (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).
