Solid State Relays

PhotoMOS relaysolid-state relay1 Form A60 V0.5 ASOP4

ST3M-Y212S is a normally open, optically isolated PhotoMOS relay for switching AC or DC loads up to 60 V and 0.5 A continuous current.

Best for

  • Low-voltage AC/DC signal and load switching
  • Optically isolated I/O and test equipment interfaces

Avoid if

  • The application requires more than 60 V peak or 0.5 A continuous load current
  • Very low conduction loss is required without thermal analysis

Check before use

  • Load voltage and continuous current
  • On-resistance power dissipation
  • LED drive current and switching timing
  • Required isolation and PCB clearance
