SI8736BC-ISR

Digital Isolators Overview

The SI8736BC-ISR is a single-channel unidirectional digital isolator from Skyworks Solutions, utilizing capacitive coupling technology. It operates within a supply voltage range of 2.5 V to 5.5 V and supports data rates up to 15 Mb/s. The device provides an isolation voltage of 3750 Vrms with a typical common-mode transient immunity (CMTI) of 25 kV/µs. Key timing parameters include a maximum propagation delay of 50 ns and rise/fall times of 4 ns. It functions reliably across an extended temperature range of -40°C to +125°C and is housed in an SOIC-8 package.

Digital Isolators Feature Summary

Digital Isolators Procurement Notes

Verify the specific suffix 'ISR' corresponds to the reel packaging format required for your assembly line. Confirm that the 3750 Vrms insulation rating meets the safety standards of your target application. Ensure compatibility with the Si871x development kit if prototyping is necessary. Check moisture sensitivity levels for proper storage handling.

Digital Isolators Selection Notes

Select this component when a single-channel unidirectional isolator is required. It is suitable for replacing traditional optocouplers in space-constrained designs. Consider the 15 Mb/s data rate limit and 50 ns delay for signal integrity requirements. The SOIC-8 package offers a compact footprint for surface mount applications.

Digital Isolators Part Context

This part belongs to the Si873x series of digital isolators. It is designed as a direct pin-compatible replacement for legacy optocouplers. The series emphasizes high CMTI and low power consumption. It complements other Skyworks isolation products like the SI8283 gate drivers.
