High Current Transfer Ratio 100% min (MCA231: 200% min).
55 volt BVceo for MCA255
The MCA230, MCA231 and MCA255 are photodarlington optically coupled
isolators consisting of an infrared emitting diode with a silicon
photodarlington transistor. Surface Mount Option Available.
All electrical parameters are 100% tested by manufacturing. Specifications
are guaranteed to a cumulative 0.65% AQL.
