Vishay Intertechnology – Automotive-grade phototransistor optocoupler comes in SOP-4 Mini-Flat package

Vishay Intertechnology has launched its first Automotive Grade phototransistor optocoupler, the VOMA617A. The new device combines a high CTR with a low forward current of 5mA in the compact SOP-4 mini-flat package, which saves 30% PCB space compared to a DIP-4 package. The device is intended for galvanic and noise isolation, battery management, signal transmission, and system control in automotive applications, as well as hybrid and electric vehicles, and high reliability industrial applications. The device offers a CTR range from 50% to 600%. The device features a GaAlAs infrared emitting diode that is optically coupled to a silicon phototransistor. The SOP-4 package provides a 3750V isolation voltage rating and creepage, and clearance distance of =5 mm. The device is molded using an eco-friendly 'green' compound, is RoHS-compliant, and in accordance with WEEE 2002/96/EC. It is certified to UL, cUL, VDE, and CQC safety standards.
