Radiation Tolerant, Phototransistor Hermetic Surface Mount Optocouplers

The OLS049 and OLS249 are radiation tolerant, phototransistor hermetic surface mount optocouplers designed specifically for hi-rel applications requiring optical isolation in radiation environments such as gamma, neutron, and proton radiation with high current transfer ratio and low saturation Vce.

Request Information

These optocouplers are comprised of a light emitting diode and a NPN silicon phototransistor that is electrically isolated yet optically coupled inside a hermetic 4-pin leadless chip carrier package. They feature high degradation characteristics due to their radiation exposure, and are available with 100% hi-rel screened parts.

Additional features include:

  • Hermetic surface mount package
  • Radiation tolerant
  • 1000 Vdc electrical isolation
  • Small footprint
  • High current transfer ratio
