Vishay Intertechnology launched its first automotive grade phototransistor optocoupler, the VOMA617A. The new device combines a high current transfer ratio (CTR) with a low forward current of 5 mA in the compact SOP-4 mini-flat package, which saves 30 % PCB space compared to the DIP-4 package.
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 device offers a CTR range from 50% to 600%.
The VOMA617A features a GaAlAs infrared emitting diode that is optically coupled to a silicon phototransistor. The SOP-4 package provides a 3750 V isolation voltage rating and creepage and clearance distance of more than 5 mm. The VOMA617A is moulded using an eco-friendly compound, RoHS-compliant and in accordance with WEEE 2002/96/EC. It is certified to UL, cUL, VDE and CQC safety standards.
