Power Phototriac eliminates need for separate power TRIAC.
September 15, 2008 -
Offered in 16-pin DIP package, VO3526 outputs currents up to 1 A to drive resistive and inductive loads. It consists of GaAs IR LED optically coupled to monolithic photosensitive non-zero-crossing TRIAC detector chip. Rated at 600 V blocking voltage, power phototriac can provide isolation between dc and ac voltages on 120 and 240 Vac lines. Along with input-to-output isolation voltage of 5,300 V, product offers 10 mA input trigger current that facilitates interface with digital logic.

Vishay's New 1-A Output Current Integrated Power Phototriac Eliminates Need for Separate Power TRIAC
MALVERN, PENNSYLVANIA - August 27, 2008 - Vishay Intertechnology, Inc. (NYSE: VSH) broadens its optoelectronics portfolio with the release of an integrated power phototriac that outputs currents up to 1A to drive resistive and inductive loads.
Offered in the 16-pin DIP package, the VO3526 consists of a GaAs infrared LED that is optically coupled to a monolithic photosensitive non-zero-crossing TRIAC detector chip. This in turn powers on an integrated power TRIAC. By eliminating the need for an external power TRIAC, the device cuts design costs and saves board space.
Rated at 600-V blocking voltage, the power phototriac can provide isolation between DC and AC voltages on 120-V and 240-V AC lines, giving designers a 2X or better safety factor. For additional safety, the device offers an input-to-output isolation voltage of 5300V. A low 10-mA input trigger current facilitates an easy interface with digital logic.
The VO3526 can be used as a solid-state relay. Optimized for noisy environments, typical applications for the new device will include home appliances such as air conditioners, refrigerators, dishwashers, washer/dryers, and oven ranges.
Samples and production quantities of the new VO3526 power phototriac are available now, with lead times of four to six weeks for large orders. Pricing for U.S. delivery in 10,000-piece quantities is $1.25.
