Toshiba Electronic Devices & Storage Corporation has expanded its digital isolator portfolio with the launch of the DCL54xx01A series, a new lineup of quad-channel high-speed standard digital isolators designed for industrial equipment operating in high-temperature environments.
The company said the ten new products are housed in SOIC16-W packages and support a maximum operating temperature of 125°C. Volume shipments began today.
According to Toshiba, the launch addresses growing demand for reliable isolation devices in industrial systems increasingly using silicon carbide (SiC) and gallium nitride (GaN) power semiconductors. These devices allow industrial equipment to operate at higher temperatures and switching speeds but also increase exposure to electrical noise during isolated signal transmission.
The company noted that electrical noise between input and output sections can lead to signal instability and system malfunctions in industrial automation systems, motor drives, and inverter applications.
Toshiba said the new digital isolators use its proprietary magnetic coupling isolation transmission technology to achieve common mode transient immunity (CMTI) of 150kV/μs (typical). The high noise immunity is designed to support stable control signal transmission in electrically noisy industrial environments.
The DCL54xx01A series is available in several channel configurations, including four forward channels, three forward channels with one reverse channel, and two forward and two reverse channels. Toshiba said the range is intended to provide flexibility for different industrial communication and control applications.
Target applications include isolated communication interfaces for industrial automation systems, I/O interfaces, motor control systems, and industrial inverters.
The company added that the new products complement its existing DCL341x0B series of standard digital isolators, which support lower power consumption and communication speeds of up to 25Mbps in compact SSOP16 packages.
Industry demand for digital isolation technologies has increased alongside wider adoption of high-efficiency power electronics in industrial equipment, renewable energy systems, and factory automation platforms.
Toshiba said it will continue developing isolation devices for industrial and automotive applications to support stable communication, equipment reliability, and carbon neutrality initiatives.
