SI8651BD-ASR

Digital Isolators Overview

The SI8651BD-ASR is a Skyworks Solutions automotive-grade digital isolator featuring five channels in a unidirectional configuration. It utilizes capacitive coupling technology to provide an insulation voltage of 5000 Vrms. The device supports data rates up to 150 Mb/s with a propagation delay of 8 ns and rise/fall times of 4 ns. Operating within a supply voltage range of 2.375 V to 5.5 V, it draws 18.4 mA of working power current. Certified under AEC-Q100 standards, it functions reliably between -40°C and +125°C. Packaged in a 16-SOIC format, the component includes a shutdown feature and exhibits a pulse width distortion of 0.2 ns.

Digital Isolators Procurement Notes

Verify that the specific part number suffix matches the required insulation rating and channel configuration. Confirm AEC-Q100 certification status is explicitly stated for the intended automotive application. Ensure the SOIC-16 package dimensions align with PCB layout constraints. Cross-reference the datasheet specifications against system requirements for voltage and temperature ranges before finalizing procurement.

Digital Isolators Selection Notes

Select this component when high-voltage isolation is required for automotive applications. The 5000 Vrms rating distinguishes it from lower-rated variants like the SI8651BB series. Consider the unidirectional nature and specific channel count for interface design. Verify compatibility with the operating temperature range and supply voltage limits defined in the technical documentation.
