Vishay VOMA618A automotive grade phototransistor optocoupler

Vishay Intertechnology introduces 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. It features a GaAlAs infrared emitting diode that is optically coupled to a silicon phototransistor. It offers 80% lower forward current than the solutions from the previous-generation to save energy in automotive and high-reliability applications. Its low-profile package saves board space.
