Addressing the accuracy and energy efficiency demands of industrial applications, Vishay Intertechnology’s VOx619A series phototransistor optocouplers combine a high and linear current transfer ratio (CTR) over temperature with a forward current of 0.5 mA. They operate in temperatures up to +125°C and are available in four package options: DIL-4, long creepage LSOP-4, compact SOP-4, and half-pitch SSOP-4.
Achieving a 50% lower forward current than the company’s previous-generation components, the optocouplers target energy-efficient designs in micro mobility, industrial, energy metering, telecom, and consumer applications. They are also viable for use with devices that have limited current-driving capabilities, such as microcontrollers (MCUs).

Other VOx619A series optocoupler features include an infrared emitting diode optically coupled to a phototransistor detector, a maximum isolation voltage of 5 kVRMS, and creepage and clearance distances of ≥7 mm and ≥8 mm, respectively. Devices in the SOP-4 and SSOP-4 specify a voltage isolation of 3.750 kVRMS and creepage and clearance distances of ≥5 mm.
Samples and production quantities of the VOx619A series are available now, with lead times of eight weeks. For deeper details, procure and peruse the VOL619A, VO619A, VOM619A, and VOS619A datasheets.
