SI8710AC-B-IP

Digital Isolators Overview

The SI8710AC-B-IP is a unidirectional digital isolator from Skyworks Solutions, designed as an optocoupler replacement in an 8-DIP Gull Wing package. It features capacitive coupling technology with a 3750 Vrms isolation voltage and supports data rates up to 15 Mbps. The device operates within a supply voltage range of 3V to 30V and maintains a low operating current of 1.7 mA. Key electrical specifications include a maximum propagation delay of 60 ns, a common-mode transient immunity of 20 kV/µs, and a pulse width distortion of 20 ns. It is qualified under AEC-Q100 standards for automotive applications and functions reliably across a temperature range of -40°C to +125°C.

Digital Isolators Feature Summary

• Provides robust galvanic isolation via capacitive coupling technology to replace traditional optocouplers.
• Features high common-mode transient immunity of 20 kV/µs for reliable signal transmission in noisy environments.
• Offers a compact 8-pin DIP gull wing footprint suitable for standard through-hole mounting.
• Includes internal logic directionality control for simplified circuit design.

Digital Isolators Applications

• Automotive electronic control units (ECUs) requiring AEC-Q100 qualified components
• Industrial motor control systems needing high-speed digital isolation
• Power supply feedback loops for isolated signal transmission
• General-purpose digital isolation in mixed-signal circuits

Digital Isolators Procurement Notes

Verify the specific suffix 'B-IP' corresponds to the 8-DIP Gull Wing package configuration when sourcing. Confirm that the manufacturer's datasheet explicitly lists this part number as an AEC-Q100 qualified component if automotive grade certification is required. Ensure compatibility with existing PCB footprints before procurement, as package dimensions may vary slightly between manufacturers. Cross-reference the latest revision history to ensure no functional changes have occurred since initial release.

Digital Isolators Selection Notes

Select this component when a unidirectional signal path with high-speed capability (15 Mbps) is required. The 3750 Vrms isolation rating makes it suitable for applications demanding significant potential difference between input and output domains. Consider the 8-DIP package form factor if through-hole assembly is preferred over surface mount alternatives. Evaluate the 60 ns propagation delay against system timing requirements to ensure signal integrity is maintained during high-frequency operations.

Digital Isolators Part Context

This device belongs to the Si871x family of digital isolators, which utilizes Skyworks' proprietary silicon capacitor technology. Unlike optical isolators, these devices offer longer lifespan, lower power consumption, and better performance consistency across temperature variations. The family includes various channel configurations and isolation voltages, with the SI8710AC-B-IP representing a single-channel, high-isolation variant optimized for general-purpose industrial and automotive use cases.
