AT817B-FeH-DE

AOTE · Transistor, Photovoltaic Output Optoisolators · DIP-4

AT817B-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 passive LED anode (input side). Forward current IF up to 50 mA continuous, 1000 mA peak (1 µs pulse); VF typ 1.2 V / max 1.4 V at IF=20 mA. Drive through a current-limit resistor; keep reverse voltage below VR=6 V.
2 CATHODE passive LED cathode (input side). Return terminal for the infrared emitter; typically tied to input-side ground/return of the drive circuit.
3 EMITTER passive Phototransistor emitter (output side). Galvanically isolated from the LED side (VISO > 5000 Vrms, 1 min). Usually tied to output-side ground/return.
4 COLLECTOR passive Phototransistor collector (output side). Maximum IC=50 mA, VCEO=80 V, PC=150 mW. Dark current ICEO ≤ 100 nA at VCE=20 V. Current transfer ratio 130%-260% (bin B) at IF=5 mA, VCE=5 V.

Provenance

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

  • Datasheet: AOTE datasheet (12 pp, sha256 29c7ba82cd4372ed, 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).
