Optocoupler, Photodarlington Output, High Gain, With Base Connection Features Isolation test voltage, 5300 VRMS Coupling capacitance, 0.5 pF Fast rise time, 10 �s Fast fall time, 35 �s UL File E52744 System Code or J DIN EN 60747-5-2(VDE0884) DIN EN 60747-5-5 pending Available with Option 1 CSA 93751 BSI DescriptionThe MCA231/ MCA255 are industry standard optocouplers, consisting of a gallium arsenide infrared LED and a silicon photodarlington. These optocouplers are constructed with a high voltage insulation packaging process which offers 7.5 kV withstand test capability. For additional option information and package dimensions see Option Section.Tamb = 25 �C, unless otherwise specified Stresses in excess of the absolute Maximum Ratings can cause permanent damage to the device. Functional operation of the device is not implied at these or any other conditions in excess of those given in the operational sections of this document. Exposure to absolute Maximum Rating for extended periods of the time can adversely affect reliability.
