Optocouplers with phototransistor output in eco-friendly green DIP and mini-flat packages
December 19, 2011 // Paul Buckley
Vishay Intertechnology is broadening the company's optoelectronics portfolio with the release of six low input current optocouplers with phototransistor output in the DIP-4, SSOP-4 half-pitch miniflat, and SOP-4L long miniflat packages. The optocouplers claim to provide exceptional isolation for human and equipment safety.
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.
Samples and production quantities of the new optocouplers are available now, with lead times of six to eight weeks for large orders.

The SoCKIT evaluation kit is Arrow's latest development tool, featuring an Altera Cyclone V SoC with a dual-core ARM Cortex-A9 MPCore processor integrated within its 28nm FPGA fabric.
Altera SoCs allow embedded system developers to differentiate their end product with customized hardware and software, and extend the product lifecycle through hardware and software updates in the field. This month, Arrow Electronics is giving away five SoCKIT evaluation kits featuring Altera’s ARM-Based SoCs, worth €249 each, together with the free entrance to one of Arrow’s SoC workshops organized throughout Europe.
And the winners are...
In our previous reader offer, Freescale Semiconductor was giving away five IMX6Q, Sabre-lite kits, worth £128.06 each.
Lucky winners include Mr. X. Salada Sole from the UK, Mrs A. Peric from Germany, Mr Z. Janosy from Hungary, Mr D. Gacina from Croatia and Mr B. Boris from France. All should be receiving their packages soon. Let's wish them some interesting findings with their projects.
