AT852-CuH-D

AOTE · Transistor Output Optocoupler · DIP-4

AT852-CuH-D from AOTE, in a DIP-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 infrared LED, driven with a forward current of 5 to 15 mA recommended (50 mA absolute maximum).
2 Cathode passive Cathode of the input infrared LED, with a reverse voltage limit of 6 V.
3 Emitter passive Emitter of the output Darlington phototransistor, with a maximum emitter-collector voltage of 7 V.
4 Collector passive Collector of the output Darlington phototransistor, with a collector-emitter voltage of 350 V maximum and a collector current of 150 mA maximum.

CAD (KiCad official)

  • Symbol: AT852-CuH-D
  • Footprint: Package_DIP:DIP-4_W7.62mm
  • 3D model: DIP-4 (KiCad packages3D, STEP)
  • 3D model files: at852-cuh-d-etched.step / at852-cuh-d-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); at852-cuh-d.step / at852-cuh-d.glb are the bare package body.

Provenance

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

  • Datasheet: AOTE datasheet (13 pp, sha256 d068747ef469b9b6, retrieved 2026-10-27, 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.
