SI8711BD-B-IMR

Digital Isolators Overview

The SI8711BD-B-IMR is a general-purpose digital isolator from Skyworks Solutions Inc. featuring capacitive coupling technology. It provides galvanic isolation with a rated insulation voltage of 5000 Vrms and supports data rates up to 15 Mb/s. The device operates within a supply voltage range of 3 V to 30 V, consuming a typical operating current of 1.7 mA. Key electrical parameters include a propagation delay of 60 ns, rise/fall times of 15 ns/5 ns, and a pulse width distortion of 20 ns. It functions reliably across an extended temperature range from -40 °C to +125 °C and is housed in an 8-LGA (10x12.5) package.

Digital Isolators Procurement Notes

Verify the specific suffix 'IMR' corresponds to the 8-LGA surface-mount package and tape-and-reel delivery format. Confirm that the component meets AEC-Q100 automotive qualification requirements if intended for automotive applications. Ensure the datasheet version matches the required insulation voltage rating of 5000 Vrms. Cross-reference pinout diagrams to guarantee compatibility with existing PCB footprints before finalizing procurement orders.

Digital Isolators Selection Notes

Select this component when replacing legacy optocouplers with higher speed and lower power consumption requirements. Choose the SI8711BD variant specifically for its 5000 Vrms isolation capability compared to lower-rated family members. Consider the 8-LGA package size constraints and thermal performance needs. Evaluate the 15 Mb/s data rate against system timing requirements to ensure adequate signal fidelity.
