- **Wide Operating Temperature Range:** Reliable performance in harsh environments.  
- **Lead-Free & RoHS Compliant:** Environmentally friendly.  

This information is strictly based on Toshiba's datasheet for the TLP280-4 photocoupler.

Application Scenarios & Design Considerations

Photocoupler GaAs Ired & Photo .Transistor

Alternative Part Number

  • PC817 --: Industry-standard single-channel optocoupler with similar CTR and isolation ratings; widely available and often used where TLP280-4 channels are split into discrete devices.
  • LTV-847 --: Quad-channel optocoupler in a DIP-16 package, functionally equivalent to the TLP280-4 multi-channel AC input optocoupler.
  • PC847 --: Quad optocoupler with AC input capability and comparable isolation voltage, suitable as a direct multi-channel replacement.
