SI8710BC-B-IPR

Digital Isolators Overview

The SI8710BC-B-IPR is a Skyworks Solutions Inc. digital isolator featuring one channel with a maximum data rate of 15 Mbps. It utilizes capacitive coupling for isolation, providing an insulation voltage of 3750 Vrms and a common-mode transient immunity (CMTI) of 35 kV/µs. The device operates within a supply voltage range of 3 V to 30 V and consumes 1.7 mA of operating current. Key timing parameters include a propagation delay of 60 ns, a rise time of 15 ns, and a fall time of 5 ns. It is housed in an 8-SMD, Gull Wing package and supports general-purpose protocols.

Digital Isolators Feature Summary

• Capacitive coupling technology ensures high reliability and long-term stability without optical degradation.
• High common-mode transient immunity of 35 kV/µs protects against noise in electrically noisy environments.
• Wide supply voltage range from 3 V to 30 V accommodates various logic levels and power domains.
• AEC-Q100 qualification supports integration into automotive applications requiring robust component standards.

Digital Isolators Applications

• General-purpose digital signal isolation between microcontrollers and peripheral devices
• Automotive electronic systems requiring AEC-Q100 qualified components
• Industrial control systems needing reliable galvanic isolation
• Power supply feedback loops for isolated gate drive signals

Digital Isolators Procurement Notes

Verify the specific suffix 'IPR' corresponds to the tape-and-reel packaging format when ordering. Confirm that the 8-SMD Gull Wing package dimensions match your PCB footprint requirements. Ensure the 3750 Vrms isolation rating meets the safety standards of your target application. Cross-reference the AEC-Q100 qualification if deploying in automotive contexts. Validate the 15 Mbps data rate sufficiency for your system's communication speed.

Digital Isolators Selection Notes

Select this component for applications requiring unidirectional signal isolation with high noise immunity. The 15 Mbps data rate suits moderate-speed digital interfaces. Consider the 60 ns propagation delay for timing-sensitive designs. The wide input voltage range simplifies interface design across different logic families. Verify thermal dissipation capabilities, as power dissipation reaches 140 mW under certain conditions.
