SI8650BC-B-IS1

Digital Isolators Overview

The SI8650BC-B-IS1 is a general-purpose digital isolator from Skyworks Solutions Inc., featuring five unidirectional channels in a 16-SOIC package. It provides 3750 Vrms isolation voltage and supports data rates up to 150 Mbps with a common-mode transient immunity of 35 kV/µs. The device operates on a supply voltage range of 2.5 V to 5.5 V, with maximum propagation delays of 13 ns for both rising and falling edges. Pulse width distortion is limited to 4.5 ns, while typical rise and fall times are 2.5 ns each. It functions within an industrial temperature range of -40°C to 125°C.

Digital Isolators Feature Summary

• Provides robust galvanic isolation via capacitive coupling technology
• Ensures signal integrity through high common-mode transient immunity
• Supports high-speed data transmission with low propagation delay
• Features a compact surface-mount package for space-constrained designs

Digital Isolators Applications

• Industrial automation control systems
• Power management circuit interfaces
• Sensor signal conditioning modules
• General-purpose isolated communication links

Digital Isolators Procurement Notes

Verify the specific suffix IS1 corresponds to the tube packaging configuration as documented in official Skyworks materials. Confirm that the BC variant meets the required thermal and electrical specifications for the target application environment. Cross-reference the manufacturer part number against current datasheets to ensure no recent design changes affect compatibility or performance ratings.

Digital Isolators Selection Notes

Select this component when five independent unidirectional isolation channels are required within a single package. The 35 kV/µs CMTI rating makes it suitable for noisy environments with rapid voltage transients. Ensure the system voltage aligns with the 2.5 V to 5.5 V operating range and that the 16-SOIC footprint fits the PCB layout constraints.

Digital Isolators Part Context

This device belongs to the Si86xx family of digital isolators, which utilize Skyworks' proprietary capacitive coupling technology. The family offers various channel counts and isolation voltages, but the SI8650 specifically addresses applications needing five channels with high-speed performance and strong transient immunity in a standard SOIC form factor.
