Automotive Grade Optocoupler with High CTR and 1mA Forward Current

March 11, 2020 by Paul Shepard

Vishay Intertechnology, Inc. has 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 1mA 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, 48V 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 3750V isolation voltage rating and creepage and clearance distance of ≥5mm. Offering low coupling capacitance of 1.2pF, 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. Pricing for U.S. delivery starts at $ 0.90 per piece.
