Toshiba Electronics Europe has launched the DCL32xx00 series, a collection of four dual-channel digital isolators. These devices are now commercially available for engineers requiring robust signal transmission in power-sensitive environments.
Why it matters
As industrial control systems scale, the need for efficient isolation between circuits with varying electrical potentials becomes critical to maintaining signal integrity. This series provides a standardized solution for designers tasked with minimizing total system power consumption.
The DCL32xx00 series achieves an operating current of 0.2mA per channel at 1Mbps and supports data rates up to 25Mbps. The components are rated for 3,000Vrms isolation and 30kV/µs common-mode transient immunity.
The players
Toshiba Electronics Europe
A division of the global technology conglomerate focusing on the distribution and development of power semiconductors and system-on-chip solutions for industrial markets.
The details
The devices utilize magnetic-coupling isolation, which uses microscopic transformer coils to transfer signals across an insulating barrier without a physical electrical connection. This replaces traditional optocouplers—components that use light to bridge an isolation barrier—which typically suffer from higher power draw and degradation over time. Integrated circuit technology within the transmission section manages the signal path, ensuring reliable operation between -40 and 125°C.
Timeline
Toshiba released the DCL32xx00 series on October 10, 2026.
The Tech Race
The transition from traditional light-based optocouplers to magnetic-coupling solutions reflects a broader industry movement toward lower-power, high-durability signal management. Toshiba's release positions its new series directly against existing isolation standards in the power-constrained industrial sector.
Engineers working on industrial control systems can immediately incorporate these devices into designs requiring a supply voltage between 2.25V and 5.5V. The compact SOIC8-N packaging ensures the series is compatible with most standard high-density board layouts.
The takeaway
Designers should monitor the integration of these isolators in high-noise industrial environments to verify if the 30kV/µs transient immunity meets performance expectations. Watch for updated technical documentation from Toshiba regarding long-term reliability benchmarks for this series.
