AT3H7D-CuH-S

AOTE · Transistor, Photovoltaic Output Optoisolators · SSOP-4

AT3H7D-CuH-S from AOTE, in a SSOP-4. 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 Anode passive Anode of the input LED; forward current IF is 5 mA min to 15 mA max recommended, 50 mA absolute maximum.
2 Cathode passive Cathode of the input LED, return path for forward current IF (50 mA absolute maximum).
3 Emitter passive Phototransistor emitter output; emitter-collector voltage VECO is 7 V maximum.
4 Collector passive Phototransistor collector output; VCEO is 80 V maximum and collector current IC is 50 mA maximum.

Key specifications

Manufacturer AOTE
Package SSOP-4
Category Optoisolators
Pins 4

CAD (KiCad official)

  • Symbol: AT3H7D-CuH-S
  • Footprint: Package_SO:SSOP-4_4.4x2.6mm_P1.27mm
  • 3D model: SSOP-4, generated from the KiCad footprint (body from the F.Fab outline, terminals on the pads, 1.75 mm nominal SSOP height). Neither the vendor nor KiCad ships a 3D model for this package, so the dimensions are nominal, not the manufacturer's CAD (STEP)
  • 3D model files: at3h7d-cuh-s-etched.step / at3h7d-cuh-s-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); at3h7d-cuh-s.step / at3h7d-cuh-s.glb are the bare package body.

Provenance

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

  • Datasheet: AOTE datasheet (12 pp, sha256 ac553ad423c97ad5, retrieved 2026-10-09, 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-sonnet-5-5 (text+vision), consensus claude-opus-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).
