This datasheet also covers the IL56B variant, as both devices belong to the same optocoupler family and are provided as variant models within a single manufacturer datasheet.
General Description
The IL5xB and MOC8021 are optically coupled isolators with a gallium arsenide infrared LED and a silicon photodarlington sensor.
Switching can be achieved while maintaining a high degree of isolation between driving and load circuits.
Key Features
High collector-emitter breakdown voltage, 80 V minimum.
High isolation resistance, 1011 Ω typical.
Standard plastic DIP Package.
No base terminal connection for improved common mode interface immunity.
Lead-free component.
Component in accordance to RoHS 2002/95/EC and WEEE 2002/96/EC
