ST3M-Y214A product

ST3M-Y214A

Component

PhotoMOS relay1 Form A400 V0.14 ASMD43750 Vrms isolation

ST3M-Y214A is a 400 V, 0.14 A normally-open PhotoMOS relay for isolated low-current AC/DC load switching in an SMD4 package.

Best for

  • Isolated low-current AC/DC switching
  • Automatic test equipment
  • I/O and sensing interfaces

Avoid if

  • Low-loss switching requires substantially less than 18 Ω on-resistance
  • Load current exceeds 0.14 A continuously
  • Compliance or lifecycle documentation is mandatory but unavailable

Check before use

  • On-state voltage drop and output power dissipation at actual load current
  • SMD4 footprint and mechanical clearance
  • Off-state leakage tolerance in the load circuit
