Low-current mini optocouplers save board space

VOS618A and VOS617A series optocouplers feature low DC input currents of 1mA (VOS618A) and 5mA (VOS617A) and are offered in DIP-4, LSOP-4, SOP-4 and SSOP-4 packages. The compact SSOP-4 mini-flat package saves more than 60% board space compared to a DIP-4 package and is ideal for space constrained applications. SOP-4, SSOP-4 and LSOP-4 products have a package height of only 2mm.

The mini optocouplers benefit from low power dissipation and extensive CTR (current transfer ratio) ranges from 40% to 600%, giving design engineers increased flexibility. Certified to UL, CSA, VDE, Fimko, and CQC safety standards, the devices are fully RoHS-compliant, lead (Pb)-free, and an eco-friendly “green” compound.

The components are designed for isolated feedback loops, I/O isolation, and isolation in switch-mode power supplies, AC adapters, motor drives, solar invertors, networking switches, telecom line cards, and home appliances.
