EL357 - DC Input Photo Transistor Coupler

General Description

The UMW EL357 series combine an AlGaAs infrared emitting diode as the emitter which is optically coupled to a silicon planar phototransistor detector in a plastic SOP4 package.

With the robust coplanar double mold structure, UMW EL357 series provide the most stable isolation feature.

Key Features

  • High isolation 3750 VRMS.
  • CTR flexibility available see order information.
  • DC input with transistor output.
  • Operating temperature range - 55 °C to 110 °C.
  • REACH compliance.
  • Halogen free.
  • MSL class 1.
  • UL Recognized: UL1577, File No. E492440.
