1. 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.

  2. Surface Mount Optocoupler: OLS449

    The OLS449 is a surface mount optocoupler featuring an LED and N-P-N silicon photo-transistor that is electrically isolated, but optically coupled inside a hermetic six-pin Leadless Chip Carrier (LLC) package. The optocoupler also has a high Current Transfer Ratio (CTR) with an ambient temperature range from -55°C to +100°C at an LED current of 1mA due to radiation exposure.
