Digital isolators strengthen industrial systems
Part of Diodes’ RobustISO family, the API782x series of dual-channel digital isolators delivers 5.7-kVRMS isolation for 1 minute per UL 1577. The devices offer reliable protection for digital control and communication signals in solar inverters, motor control, industrial automation, and data center equipment.
The API782x series meets reinforced and basic isolation requirements across multiple standards, including VDE, UL, and CQC. The devices are rated for an 8-kV peak isolation voltage per DIN VDE 0884-17 and a 12.8-kV peak surge isolation voltage for transient events. Based on Diodes’ reliability calculations for the capacitive isolation barrier, the components offer a predicted operational lifetime exceeding 40 years.
The isolators support data rates up to 100 Mbps and provide a minimum CMTI of 150 kV/µs. The API7820 features both channels in the same direction, while the API7821 provides both channels in the opposite direction with either a high or low default output state. They operate from a 2.5-V to 5.5-V supply voltage and typically consume 2.1 mA per channel at 1 Mbps.
API782x isolators in SO-16WW packages are available through Diodes’ authorized distributors.
