Device Combines High CTR Range With Low Forward Current of 1 mA for Automotive and High Reliability Industrial Applications

Vishay Intertechnology, Inc. (NYSE: VSH) today introduced a new Automotive Grade phototransistor optocoupler that combines a high current transfer ratio (CTR) range from 50 % to 600 % with a low forward current of 1 mA in the compact SOP-4 mini-flat package.

Offering 80 % lower forward current than the previous-generation solution, the Vishay Semiconductors VOMA618A is designed to save energy in automotive and high reliability applications, while its low profile package saves board space. The AEC-Q101 qualified device is optimized for galvanic and noise isolation, signal transmission, battery management, 48 V boardnets, and system control in hybrid and electric vehicles.

The VOMA618A features a GaAlAs infrared emitting diode that is optically coupled to a silicon phototransistor. Its SOP-4 mini-flat package provides a 3750 V isolation voltage rating and creepage and clearance distance of ≥ 5 mm. Offering low coupling capacitance of 1.2 pF, the device is RoHS-compliant, halogen-free, and Vishay Green.

Samples and production quantities of the VOMA618A are available now, with standard lead times of four to six weeks.
