SI8423AB-D-IS

Digital Isolators Overview

The SI8423AB-D-IS is a Skyworks Solutions digital isolator featuring two unidirectional channels in an 8-pin SOIC-N package. It operates on a supply voltage range of 2.7 V to 5.5 V with a maximum power dissipation of 150 mW. The device provides 2500 Vrms isolation via capacitive coupling and supports data rates up to 1 Mb/s. Key electrical parameters include a propagation delay of 35 ns, rise/fall times of 4 ns, and a common-mode transient immunity of 20 kV/µs. It functions within a temperature range of -40°C to +125°C.

Digital Isolators Feature Summary

• Capacitive coupling technology for signal transmission across isolation barrier
• Integrated shutdown control for low-power management
• High common-mode transient immunity capability
• Unidirectional channel configuration

Digital Isolators Applications

• General-purpose digital isolation
• Industrial process control systems
• Power monitoring equipment

Digital Isolators Procurement Notes

Verify the specific suffix 'D' indicates the standard tube packaging format rather than tape-and-reel variants like 'ISR'. Confirm RoHS compliance status through official manufacturer documentation before procurement. Ensure the component meets required humidity sensitivity level (MSL) handling protocols during storage and assembly processes.

Digital Isolators Selection Notes

Select this component when unidirectional isolation is sufficient for the application design. The 1 Mbps data rate suits lower-speed communication interfaces compared to higher-performance models in the series. Verify that the 2500 Vrms isolation rating aligns with safety standards required by the target system environment.
