Description
The OPI210 and OPI211 are optically coupled isolators each consisting of a gallium aluminum arsenide LED and a silicon phototransistor mounted and coupled on a thick film ceramic substrate. These solid-state optocouplers are ideal for hybrid applications. Four thick film bonding pads make electrical connections easy.
The OPI210 and OPI211 are identical except for the DC current transfer ratio. Both were designed with high reliability in mind and are ideally suited for use in MIL-STD-883 hybrid applications.
Device mounting may be achieved using silver or gold filled epoxies. The OPI210 and OPI211 are sensitive to some hybrid cleaning processes. Consult factory for details.
