Component

PhotoMOS relaysolid-state relaydual channelnormally openSMD8400 V

ST3M-W214A is a dual-channel, normally open PhotoMOS relay in an SMD8 package for switching AC or DC loads up to 400 V and 0.14 A continuously.

Best for

  • Isolated switching of low-current AC or DC signals
  • Test, sensing, communication, security, and I/O equipment

Avoid if

  • The load exceeds 0.14 A continuously or 400 V peak
  • Very low switch resistance or high power switching capability is required

Check before use

  • SMD8 footprint and pin pitch
  • Load-current derating versus ambient temperature
  • Input LED drive current and output dissipation
