SI8650BB-B-IS1

Digital Isolators Overview

The SI8650BB-B-IS1 is a general-purpose digital isolator manufactured by Skyworks Solutions Inc. It features five unidirectional channels with a data rate of 150Mbps and an isolation voltage of 2500Vrms. The device operates within a supply voltage range of 2.5V to 5.5V and supports a common mode transient immunity (CMTI) of 35kV/µs. Propagation delay is typically 13ns, with rise and fall times of 4ns. It is housed in a 16-SOIC package and functions across a temperature range of -40°C to 125°C.

Digital Isolators Feature Summary

• Capacitive coupling technology provides robust signal isolation without magnetic interference.
• High common mode transient immunity ensures reliable operation in noisy environments.
• Unidirectional channel configuration simplifies interface design for single-direction data flow.

Digital Isolators Applications

• Industrial automation control systems
• Power supply feedback loops
• Medical equipment signal isolation

Digital Isolators Procurement Notes

Verify the specific suffix 'B' against official Skyworks documentation to confirm insulation rating and package width variations. Ensure the 'IS1' designation matches the required tape and reel or tube packaging format. Cross-reference the manufacturer part number with the latest datasheet revision to confirm compliance with current RoHS standards and AEC-Q100 qualification status before finalizing procurement orders.

Digital Isolators Selection Notes

Select this component when five isolated channels are required for high-speed data transmission up to 150Mbps. The 2500Vrms isolation rating suits applications requiring moderate electrical separation between low-voltage logic and higher-voltage power stages. Consider the 16-SOIC footprint for PCB layout constraints and verify that the 35kV/µs CMTI meets the noise immunity requirements of the target system environment.

Digital Isolators Part Context

This part belongs to the Si865x series of digital isolators from Skyworks Solutions. The series utilizes capacitive coupling technology to provide isolation between circuits. The SI8650 variant specifically offers five channels, distinguishing it from other members of the family that may offer fewer or more channels. It is designed for general-purpose applications requiring reliable signal transfer across isolation barriers.

Digital Isolators Replacement Considerations

SI8650BC-B-IS1: Offers higher 3750Vrms isolation rating with identical channel count and pinout. SI8650BD-B-IS: Provides 5000Vrms isolation capability while maintaining the same 5-channel architecture and SOIC-16 package form factor.
