SI8655BA-AS1

Digital Isolators Overview

The SI8655BA-AS1 is a Skyworks Solutions automotive-grade digital isolator featuring five unidirectional channels in a 16-SOIC package. It operates on a 2.375 V to 5.5 V supply with an 8 ns propagation delay and 4 ns rise/fall times. The device provides 5000 Vrms insulation via capacitive coupling, supports 150 Mb/s data rates, and offers 35 kV/µs common-mode transient immunity. It functions within a -40°C to +125°C temperature range and includes a shutdown feature.

Digital Isolators Feature Summary

• Provides high-voltage galvanic isolation for automotive applications using capacitive coupling technology.
• Features five independent unidirectional signal paths with integrated shutdown control.
• Delivers fast signal transmission with low propagation delay and minimal pulse width distortion.

Digital Isolators Applications

• Automotive powertrain control systems
• Inverter gate drive circuits
• Motor control interfaces

Digital Isolators Procurement Notes

Verify the specific suffix AS1 against official Skyworks documentation to confirm the SOIC-Wide-16 package and 5000 Vrms rating. Ensure AEC-Q100 qualification status aligns with project requirements. Confirm moisture sensitivity level handling procedures during assembly.

Digital Isolators Selection Notes

Select this component when high voltage isolation exceeding 1000 Vrms is required alongside automotive reliability standards. Compare against lower-rated variants like the BA series if system voltage permits. Evaluate channel count needs against alternative Si86xx family members.

Digital Isolators Part Context

This part belongs to the Si865x family of digital isolators from Skyworks Solutions. These devices utilize proprietary CMOS process technology to replace traditional optocouplers. The family offers various channel counts and insulation ratings tailored for industrial and automotive interface applications.

Digital Isolators Replacement Considerations

SI8655BD-B-ISR: Similar 5-channel isolator but features a wider SOIC package and reel packaging.
