TLP785GB

AOTE · Transistor, Photovoltaic Output Optoisolators · DIP-4

TLP785GB 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 LED anode (input side); the page 4 absolute maximum reverse voltage VR is 6 V.
2 Cathode passive LED cathode (input side); the page 4 absolute maximum reverse voltage VR is 6 V and peak forward current IFP is rated for a 1 us pulse.
3 Emitter passive Phototransistor emitter (output side); the page 4 emitter-collector breakdown voltage BVECO is at least 7 V.
4 Collector passive Phototransistor collector (output side); the page 4 collector-emitter voltage VCEO is 80 V maximum.

CAD (KiCad official)

  • Symbol: TLP785GB
  • Footprint: Package_DIP:DIP-4_W7.62mm
  • 3D model: DIP-4 (KiCad packages3D, STEP)
  • 3D model files: tlp785gb-etched.step / tlp785gb-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); tlp785gb.step / tlp785gb.glb are the bare package body.
