Phototransistor optocoupler saves energy in automotive applications
An automotive-grade phototransistor optocoupler, released by Vishay Intertechnology, combines a high current transfer ratio (CTR) ranging from 50 to 600 per cent with a low forward current of 1mA and saves space by virtue of its compact SOP-4 mini-flat package.
According to the company, the Vishay Semiconductors VOMA618A offers 80 per cent lower forward current than the previous-generation solution. It is AEC-Q101-qualified and is optimised for galvanic and noise isolation, signal transmission, battery management, 48V boardnets and system control in hybrid and electric vehicles.
The VOMA618A features a GaAlAs infra red emitting diode that is optically coupled to a silicon phototransistor. The SOP-4 mini-flat package provides a 3,750V isolation voltage rating and creepage and clearance distance of more than or equal to 5.0mm.
It is RoHS-compliant and halogen-free and offers low coupling capacitance of 1.2pF.
Samples and production quantities of the VOMA618A are available now. Standard lead times are four to six weeks.
Vishay Intertechnology manufactures discrete semiconductors (diodes, MOSFETs, and infrared optoelectronics) and passive electronic components (resistors, inductors, and capacitors). These components are used in virtually all types of electronic devices and equipment, in the industrial, computing, automotive, consumer, telecommunications, military, aerospace, power supplies, and medical markets.
