SI8283ED-ASR

Isolators - Gate Drivers Overview

The SI8283ED-ASR is an automotive-grade, current-isolated gate driver designed for Silicon Carbide (SiC) and IGBT applications. It features a single-channel configuration with inverting and non-inverting outputs. The device utilizes Skyworks’ iCoupler technology for galvanic isolation. Key electrical parameters include a peak output current of 4A, a propagation delay of 50ns, and a common-mode transient immunity of 35kV/µs. It operates within a supply voltage range of 2.8V to 5.5V and supports junction temperatures from -40°C to 125°C.

Isolators - Gate Drivers Feature Summary

• Provides galvanic isolation using iCoupler magnetic technology for high reliability.
• Optimized for driving wide-bandgap SiC and standard IGBT power switches.
• Delivers high peak output current capability for fast switching transitions.
• Certified to AEC-Q100 standards for automotive environment durability.

Isolators - Gate Drivers Procurement Notes

Verify the specific suffix 'ED' against official Skyworks documentation to confirm package type and tape/reel specifications. Confirm RoHS compliance status through the manufacturer's latest certification records. Ensure the component meets AEC-Q100 grade requirements for your specific automotive application tier before finalizing procurement.

Isolators - Gate Drivers Selection Notes

Select this component when a single-channel isolated driver with high peak current is required for SiC or IGBT modules. Consider the 50ns propagation delay and 35kV/µs CMTI for system timing and noise immunity constraints. Compare against the SI8283CC variant if different packaging or qualification levels are needed.

Isolators - Gate Drivers Part Context

This part belongs to the Si8283 family of automotive isolated gate drivers. It shares functional similarities with other members like the SI8281 and SI8284 but differs in channel count and integrated features. The family is characterized by robust isolation barriers and high-speed performance suitable for modern electric vehicle power electronics.

Isolators - Gate Drivers Replacement Considerations

Official substitutes within the same family include SI8283CC-ISR. Verify pinout compatibility and isolation voltage ratings before substitution. Cross-referencing with similar Skyworks parts requires checking datasheet revisions for any changes in electrical characteristics or package dimensions.
