Phototransistor optocoupler saves energy and space
An 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 has been introduced by Vishay Intertechnology.
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 optimised for galvanic and noise isolation, signal transmission, battery management, 48 V boardnets, and system control in hybrid and electric vehicles.
It 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.
