SI8650BC-B-IS1R

Digital Isolators Overview

The SI8650BC-B-IS1R is a general-purpose digital isolator from Skyworks Solutions Inc., featuring five unidirectional channels with a 3750 Vrms isolation voltage. It utilizes capacitive coupling technology to achieve a data rate of 150 Mbps and a maximum propagation delay of 8 ns. The device operates on a supply voltage range of 2.375 V to 5.5 V, with a typical power consumption of 415 mW. It is housed in a 16-SOIC narrow package and supports an operating temperature range from -40°C to +125°C. This component holds AEC-Q100 qualification for automotive applications.

Digital Isolators Feature Summary

• Provides robust galvanic isolation via capacitive coupling technology
• Supports high-speed data transmission up to 150 Mbps
• Features five independent unidirectional signal channels
• Qualified for automotive environments under AEC-Q100 standards

Digital Isolators Applications

• Automotive electronic control units (ECUs)
• Industrial communication interfaces
• Power supply monitoring circuits
• Sensor interface modules

Digital Isolators Procurement Notes

Verify the specific suffix 'IS1R' confirms the reel packaging format rather than tube distribution. Ensure the order matches the BC grade specifications for temperature and performance. Confirm that the AEC-Q100 qualification status aligns with project requirements. Cross-reference the manufacturer part number against official Skyworks documentation to avoid counterfeit components.

Digital Isolators Selection Notes

Select this component when five isolated channels are required within a single package footprint. The 3750 Vrms rating suits applications needing standard industrial isolation levels. Consider the 150 Mbps speed limit for bandwidth constraints. The SOIC-16 package offers a balance between pin count and board space efficiency compared to wider packages.

Digital Isolators Part Context

This part belongs to the Si865x series of digital isolators. It shares the core architecture with other variants like the SI8650BC-B-IS1 but differs in packaging configuration. The series is designed to replace traditional optocouplers in modern systems.

Digital Isolators Replacement Considerations

Direct substitutes include the SI8650BC-B-IS1 for tube packaging or the SI8650BD-B-ISR for higher isolation ratings. Verify channel count and voltage ratings before swapping.
