• High electromagnetic immunity via capacitive coupling
• Dual independent channel configuration

Isolators - Gate Drivers Applications

• Automotive power electronics
• Motor control systems
• Inverter drives

Isolators - Gate Drivers Procurement Notes

Verify the specific suffix 'AS3' indicates reel packaging versus tube variants like 'AS'. Confirm AEC-Q100 compliance status for your specific quality requirements. Check lead times as availability may vary by region. Ensure the 14-SOIC footprint matches your PCB design constraints before ordering.

Isolators - Gate Drivers Selection Notes

Select this component when automotive certification and high noise immunity are required. Compare against SI82391BD-AS if tube packaging is preferred over reel. Consider the 3250 Vrms isolation limit against system voltage requirements. Evaluate the 4 A drive strength against gate charge demands of target switches.

Isolators - Gate Drivers Part Context

This part belongs to the Si8239x series of isolated gate drivers. It shares functional similarities with other members like SI82391BD-IS3 but differs in automotive qualification and packaging type. The series utilizes Skyworks' proprietary capacitive isolation technology for signal transmission across the isolation barrier.

Isolators - Gate Drivers Replacement Considerations

SI82391BD-AS is a compatible alternative differing primarily in tube packaging instead of reel. Verify pinout compatibility and electrical specifications match before substitution.
