Toshiba Electronics Europe has expanded its lineup of standard digital isolators with the introduction of the DCL52xx00 series, a family of dual-channel, high-speed digital isolators designed for industrial and automotive equipment.
The four new devices support reliable operation with a high common-mode transient immunity (CMTI) of 100 kV/µs (typ.) and high-speed data transfer up to 150 Mbps.
The DCL520C00 and DCL520D00 offer two forward channels, while the DCL521C00 and DCL521D00 feature one forward and one reverse channel. With these additions, Toshiba’s portfolio now includes 14 digital isolators, complementing the quad-channel DCL54xx01 series and providing engineers with a wide range of channel configurations.
Using Toshiba’s proprietary magnetic-coupling isolation technology, the DCL52xx00 series achieves stable, high-speed data transmission with a typical propagation delay of 10.9 ns and low pulse-width distortion of 0.8 ns. These characteristics enable reliable, real-time control and communication in electrically noisy environments, such as industrial automation systems, motor drives, and automotive power electronics.
Toshiba has already begun mass production of these devices for both industrial and automotive use. Recent AEC-Q100-compliant versions extend applicability to vehicle systems—including electric vehicle (EV) powertrains, onboard chargers, and battery management systems—where isolation and high-speed communication are critical. The company plans to expand package options and channel counts to support broader system architectures.
Toshiba continues to develop isolation devices and photocouplers that meet the performance, reliability, and real-time communication requirements of next-generation industrial and automotive designs.
