Vishay Intertechnology extends its optoelectronics portfolio with the release of two series of 4-pin optocouplers. They offer a high CTR (Current Transfer Ratio) from 40% to 600% at low input currents of down to 1mA and a phototransistor output. The new series in the ultra-compact SSOP-4 mini-flat package are available at distributor Rutronik as of now. The new series VOS618A and VOS617A feature low DC input currents of 1mA (VOS618A) and 5mA (VOS617A). They 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. The devices protect equipment users from electrical shocks and the microprocessors within these systems from being damaged by voltage spikes. The optocouplers, also known as opto-isolators, in the compact half-pitch mini-flat package save more than 60% board space compared to a DIP-4 package. Their package provides a 3750VRMS isolation voltage rating, a half lead pitch of 1.27mm (50 mils), package height of 2mm and creepage and clearance distance of =5mm. To provide designers with increased flexibility, the series offer a variety of of current transfer ratio of up to 600%. They feature a GaAs infrared emitting diode, which is optically coupled to a silicon planar phototransistor detector. All product information stated in the current press release is based on the franchise situation in Germany. Country specific variations may therefore be possible. Rutronik
