MOC8050 PHOTODARLINGTON OPTOCOUPLER FEATURES • High Current Transfer Ratio 500% at 50 mA Output • High Collector to Emitter Breakdown Voltage: 80 V Min. • High Isolation Voltage VISO=5300 VACRMS • Base Lead Not Connected • Solid State Reliability • Standard DIP Package • Underwriters Lab File #E52744 V • VDE 0884 Availablle with Option 1 D E DESCRIPTION The MOC8050 is an optically coupled isolator with a Gallium Arsenide infrared emitter and a silicon photodarlington sensor. Switching can be achieved while maintaining a high degree of isolation between driving and load circuits, with no cross talk between channels. These optocouplers can be used to replace reed and mercury relays with advantages of long life, high speed switching and elimination of magnetic fields.
