SI8631BT-ASR

Digital Isolators Overview

The SI8631BT-ASR is a Skyworks Solutions digital isolator featuring three channels with a unidirectional configuration. It utilizes capacitive coupling technology to provide an isolation voltage of 5000 Vrms and supports data rates up to 150 Mb/s. The device operates within a supply voltage range of 2.5 V to 5.5 V, drawing a typical operating current of 3.9 mA. It offers a propagation delay of 8 ns with rise and fall times of 4 ns. Packaged in a 16-SOIC format, it withstands a common-mode transient immunity of 60 kV/µs and functions across a temperature range of -40°C to +125°C.

Digital Isolators Procurement Notes

Verify the specific suffix ASR against official Skyworks documentation to confirm reel packaging and automotive grade status. Ensure compatibility with 16-SOIC footprint requirements. Cross-reference datasheet revisions for any updates to electrical characteristics or thermal limits before finalizing procurement specifications.

Digital Isolators Selection Notes

Select this component when unidirectional isolation is required for automotive applications. The 150 Mb/s data rate suits standard communication protocols. Verify that the 5000 Vrms isolation rating meets system safety standards. Confirm that the 16-SOIC package dimensions fit the target PCB layout constraints.

Digital Isolators Part Context

This part belongs to the Si863x series of digital isolators from Skyworks Solutions. It complements other variants like SI8631BT-IS by offering specific automotive qualification and reel packaging options. The series focuses on low-power, high-reliability isolation for demanding environments.

Digital Isolators Replacement Considerations

SI8631BT-IS serves as a non-automotive equivalent with identical electrical parameters but different packaging or qualification levels.
