Solid State Relays

photo relayMOSFET outputSMD45000 Vrms isolation400 V peak AC120 mA load current

AT214-CuH-S is a 4-pin SMD MOSFET photo relay for isolated low-current load switching up to 400 V peak AC and 0.12 A continuous current.

Best for

  • Isolated low-current AC or bidirectional load switching
  • Industrial control interfaces
  • Appliance and security-system control

Avoid if

  • Continuous load current above 0.12 A
  • Applications requiring fast switching at microsecond-scale maximum timing
  • Designs requiring confirmed lifecycle or authorized-source information

Check before use

  • 400 V peak AC load-voltage limit
  • Thermal derating at elevated ambient temperature
  • Maximum 20 Ω output on-resistance
  • PCB creepage and isolation requirements
