AT252A-CUH-S

Component

PhotoMOS relaySolid-state relaySPST normally open60 V2 ASMD-65000 Vrms isolation

AT252A-CuH-S is an SMD-6 normally-open PhotoMOS relay for isolated switching of loads up to 60 V and 2 A.

Best for

  • Isolated low-level analog signal control
  • Industrial and measurement switching
  • Sensor and security equipment interfaces

Avoid if

  • Applications requiring a confirmed lifecycle status
  • Loads that exceed the thermal limits imposed by output on-resistance
  • Applications requiring switching faster than the specified millisecond range

Check before use

  • Confirm 2 A load-current derating over ambient temperature
  • Calculate output dissipation using the applicable on-resistance
  • Drive the input LED within its 50 mA maximum forward-current rating
  • Confirm SMD-6 footprint and package orientation
