AT817C-FeH-DE

AOTE · Transistor, Photovoltaic Output Optoisolators · DIP-4

AT817C-FeH-DE from AOTE, in a DIP-4. Pinout and pin descriptions extracted from the manufacturer datasheet by ds2sf; symbol, footprint, and 3D from KiCad-official CAD.

Pinout

Pin Name Type Function
1 Anode input LED anode of the input-side GaAs infrared emitter. Drive with forward current IF (max 50 mA DC, 1000 mA pulsed 1 us); typical VF ~1.2 V at IF=20 mA. Use a series current-limiting resistor.
2 Cathode input LED cathode of the input-side infrared emitter. Reverse voltage rated to VR=6 V max. Return path for the LED drive current.
3 Emitter output Emitter of the output-side NPN silicon phototransistor. Typically tied to the output-side ground/reference. VECO breakdown 6 V max.
4 Collector output Collector of the output-side NPN phototransistor. Sinks collector current IC (max 50 mA) modulated by the LED photocurrent. BVCEO >= 80 V; VCE(sat) typ 0.1 V (max 0.2 V) at IF=20 mA, IC=1 mA.

  • Footprint: Package_DIP:DIP-4_W7.62mm
  • 3D model: DIP-4 (KiCad packages3D, STEP)
  • 3D model files: at817c-feh-de-etched.step / at817c-feh-de-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); at817c-feh-de.step / at817c-feh-de.glb are the bare package body.

Provenance

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

  • Datasheet: AOTE datasheet (12 pp, sha256 6b8be713aab0a028, retrieved 2026-08-17, 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: ds2sf (Claude). Every pin and dimension is cited to a datasheet page; it refuses to fabricate.
  • CAD: KiCad official libraries (CC-BY-SA 4.0).
