Vishay releases six low input current optocouplers with phototransistor output in eco-friendly green DIP and mini-flat packages
The VO617A and VO618A devices, available in the DIP-4 package, claim to offer excellent high-temperature performance and an isolation voltage of 5000 VRMS for switch mode power supply applications. A current transfer ratio (CTR) of 40 % to 320 % is achieved for the VO617A at input drive current of 5 mA and at 1 mA for the VO618A. Option 6 offers a creepage distance of ≥ 8 mm.
The VOL617A and VOL618A optocouplers are offered in a low-profile (2 mm) SOP-4L package with ≥ 8 mm creepage distance and an isolation voltage of 5000 VRMS. Optimized for AC adapter applications, the VOL617A and VOL618A have a CTR range of 40 % to 320 % at an input drive current of 5 mA and 1 mA respectively.
The VOS618A and VOS628A, in the small SSOP-4 package with an isolation voltage of 3750 VRMS, are suited for programmable logic controller and industrial automation applications. These devices have a CTR range of 63% to 320% at a low input drive current of 1 mA. The lower input currents reduce the amount of heat generated and complement the industry’s move to lower-power products.
The VO617A, VO618A, VOL617A, and VOL618A optocouplers are manufactured using an eco-friendly “green” molding compound.
Availability
Samples and production quantities of the new optocouplers are available now, with lead times of six to eight weeks for large orders.
