TOSHIBA · Transistor, Photovoltaic Output Optoisolators · DIP-4

TLP781 from TOSHIBA, 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 gallium arsenide infrared emitting diode (input side), whose reverse voltage rating VR is 5 V maximum and whose forward current is rated 60 mA maximum.
2 Cathode passive Cathode of the gallium arsenide infrared emitting diode (input side), with a reverse voltage rating VR of 5 V.
3 Emitter passive Emitter of the silicon phototransistor (output side), with an emitter-collector voltage VECO rating of 7 V.
4 Collector passive Collector of the silicon phototransistor (output side), rated for collector-emitter voltage VCEO of 80 V and collector current IC of 50 mA maximum.

  • Symbol: TLP781
  • Footprint: Package_DIP:DIP-4_W7.62mm
  • 3D model: DIP-4 (KiCad packages3D, STEP)
  • 3D model files: tlp781-etched.step / tlp781-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); tlp781.step / tlp781.glb are the bare package body.
