Toshiba has released the DCL32xx00 dual-channel digital isolator series to expand its portfolio of low-power industrial components. These devices utilize proprietary magnetic coupling technology to support data rates up to 25 Mbps.
Why it matters
The new series enables engineers to select isolators tailored to specific channel requirements, preventing the need for over-provisioning in industrial designs. Additionally, these units bridge 3.3 V and 5 V logic domains, eliminating the requirement for external level-shifting hardware.
The DCL32xx00 devices operate at 0.2 mA per channel and support a 3,000 Vrms isolation rating. Each SOIC8-N unit measures 4.9mm x 6.0mm x 1.75mm and maintains functionality across a supply voltage range of 2.25 V to 5.5 V.
The players
Toshiba
Toshiba is a global manufacturing conglomerate that develops a wide array of semiconductors, electronic components, and industrial equipment.
The details
Featuring four models—the DCL320C00, DCL320D00, DCL321C00, and DCL321D00—the series uses coreless transformers to provide 30 kV/μs of common-mode transient immunity. The configuration options include either two forward channels or a mix of one forward and one reverse channel.
Timeline
Mid-2026: Toshiba released its quad-channel DCL34xx0B series.
October 27, 2026: Toshiba introduced the new DCL32xx00 dual-channel series.
The Tech Race
This release reflects the broader industry move toward increasing density in power management components through proprietary magnetic coupling and coreless transformers. By expanding its catalog beyond the DCL34xx0B quad-channel series, Toshiba is positioning itself to compete in space-constrained industrial environments that require precise channel matching.
Engineers and product designers can now utilize these compact components to simplify circuit board layouts and reduce the number of external parts needed for logic level conversion. The high operating temperature tolerance allows for reliable use in demanding industrial environments.
The takeaway
These components provide an efficient solution for bridging different voltage domains in industrial systems without the need for additional level-shifting hardware. Manufacturers looking to optimize their designs for power and space should consider how matching channel counts can reduce board complexity.
