AT4N27-CuH-D

AOTE · Transistor, Photovoltaic Output Optoisolators · DIP-6

AT4N27-CuH-D from AOTE, in a DIP-6. 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, with a forward current of 5 to 15 mA recommended and 50 mA absolute maximum.
2 Cathode passive Cathode of the input infrared LED, with a reverse voltage of 6 V absolute maximum.
3 NC unconnected No internal connection.
4 Emitter passive Phototransistor emitter, where the emitter-collector voltage is 7 V absolute maximum.
5 Collector passive Phototransistor collector, where the collector-emitter voltage is 30 V absolute maximum and the collector current is 100 mA absolute maximum.
6 Base passive Phototransistor base, where the collector-base voltage is 70 V absolute maximum.

CAD (KiCad official)

  • Symbol: AT4N27-CuH-D
  • Footprint: Package_DIP:DIP-6_W7.62mm
  • 3D model: DIP-6 (KiCad packages3D, STEP)
  • 3D model files: at4n27-cuh-d-etched.step / at4n27-cuh-d-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); at4n27-cuh-d.step / at4n27-cuh-d.glb are the bare package body.

Provenance

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

  • Datasheet: AOTE datasheet (12 pp, sha256 39e9c8c142f6056a, retrieved 2026-11-05, 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.
