Low input current optocouplers in SSOP-4 mini-flat package
The VOS618A and VOS617A series are designed for isolated feedback loops, I/O isolation, and isolation. The devices protect equipment users from electrical shocks and protect the microprocessors within these systems from being damaged by voltage spikes. To provide designers with increased flexibility, the half-pitch mini-flat VOS618A and VOS617A series offer a variety of current transfer ratio (CTR) ranges from 40 % to 600 %. The devices, also known as opto-isolators, feature a GaAs infrared emitting diode, which is optically coupled to a silicon planar phototransistor detector. Their SSOP-4 package provides a 3750 VRMS isolation voltage rating, a half lead pitch of 1.27 mm (50 mils), package height of 2 mm, and creepage and clearance distance of ≥ 5 mm. The devices are molded using an eco-friendly "green" compound, and they are compliant to RoHS Directive 2011/65/EU. They are certified to UL, CSA, VDE, FIMKO, and CQC safety standards.
