Vishay Launches First Automotive Phototransistor Optocoupler
AEC-Q101 qualified device features a GaAlAs infrared emitting diode optically coupled to a silicon phototransistor
Vishay Intertechnology has launched its first automotive grade phototransistor optocoupler, the VOMA617A.
The new device which comes in a space-saving SOP-4 mini-flat package is based on a GaAlAs infrared emitting diode optically coupled to a silicon phototransistor. It features a high current transfer ratio (CTR) from 50 percent to 600 percent with a low forward current of 5 mA.
The VOMA617A is designed for galvanic and noise isolation, signal transmission, battery management, and system control in automotive applications, including hybrid and electric vehicles, as well as high reliability industrial applications.
The SOP-4 package saves 30 percent PCB space compared to the DIP-4 package, according to Vishay and provides a 3750 V isolation voltage rating and creepage and clearance distance of â‰¥ 5 mm.
Samples and production quantities of the new optocoupler are available now, with standard lead times of six to eight weeks.
