SI8650BB-AS1

Digital Isolators Overview

The SI8650BB-AS1 is a five-channel digital isolator from Skyworks Solutions, designed for automotive applications. It features capacitive coupling technology with a 2.5 kVrms isolation voltage rating. The device supports unidirectional signal transmission across all five forward channels at data rates up to 150 Mb/s. Operating on a supply voltage range of 2.5 V to 5.5 V, it exhibits a typical propagation delay of 8 ns and consumes approximately 7 mA of quiescent current. Packaged in a 16-SOIC surface-mount format, it functions reliably within an industrial temperature range of -40°C to +125°C.

Digital Isolators Procurement Notes

Verify the specific suffix AS1 against official Skyworks documentation to confirm packaging configuration and tape-and-reel specifications. Ensure that the automotive qualification status aligns with project requirements by cross-referencing the latest datasheet revision. Confirm lead times directly with authorized distributors as production schedules may vary. Validate that the 16-SOIC footprint matches the target PCB design constraints before finalizing procurement orders.

Digital Isolators Selection Notes

Select this component when five isolated channels are required for automotive environments with moderate speed needs. The 2.5 kVrms rating suits applications where lower isolation stress is acceptable compared to higher-voltage variants. Consider the 150 Mb/s limit for signal integrity; faster protocols may require alternative models. The low power consumption makes it suitable for thermally constrained automotive enclosures where heat dissipation is limited.

Digital Isolators Part Context

This part belongs to the Si865x family of digital isolators, which utilizes Skyworks' proprietary capacitive isolation architecture. The family offers various channel counts and isolation ratings to address diverse interface requirements. The SI8650BB-AS1 specifically targets the automotive segment, ensuring compliance with stringent environmental and reliability standards expected in vehicle electronics manufacturing and operation.

Digital Isolators Replacement Considerations

Direct substitutes include other parts within the Si865x series such as the SI8650BD-B-IS for higher isolation or SI8651AB-AS1 for slower speeds. Verify pin compatibility and thermal performance when swapping between different isolation voltage ratings within the same package type.
