SI8662BD-ASR

Digital Isolators Overview

The SI8662BD-ASR is a Skyworks Solutions digital isolator featuring six channels with four forward and two reverse directions. It utilizes capacitive coupling technology to provide an insulation voltage of 5000 Vrms. The device supports data rates up to 150 Mb/s with a propagation delay of 8 ns. It operates within a supply voltage range of 2.375 V to 5.5 V and consumes 26.2 mA of working power current. The component is housed in a SOIC-16 package, meets AEC-Q100 automotive qualification standards, and functions across a temperature range of -40°C to +125°C.

Digital Isolators Feature Summary

• Capacitive coupling isolation for high-speed signal transmission
• Automotive-grade reliability with AEC-Q100 certification
• Integrated bidirectional channel configuration

Digital Isolators Applications

• Automotive electronic control units
• Industrial motor drive systems
• Power supply monitoring circuits

Digital Isolators Procurement Notes

Verify the specific suffix ASR against official Skyworks documentation to confirm tape-and-reel packaging specifications. Ensure the selected variant matches the required insulation voltage and channel directionality for the target application. Cross-reference the AEC-Q100 qualification status if automotive compliance is mandatory. Confirm the SOIC-16 footprint dimensions match the design layout requirements.

Digital Isolators Selection Notes

Select this model when high insulation voltage and automotive qualification are required. Compare the 150 Mb/s speed against lower-speed alternatives if bandwidth constraints exist. Evaluate the 26.2 mA current consumption against system power budgets. Consider the bidirectional channel mix for complex signal routing needs.

Digital Isolators Part Context

This component belongs to the Si866x series of digital isolators from Skyworks Solutions. The series offers various configurations differing in insulation voltage, channel count, and directionality. The SI8662BD-ASR specifically provides a 5 kV rating and a mixed forward/reverse channel setup suitable for demanding industrial and automotive environments.

Digital Isolators Replacement Considerations

SI8662BD-B-ISR: Similar 5 kV specification but uses SOIC-Wide-16 packaging instead of SOIC-16. Verify pinout compatibility before substitution. Other SI8662 variants may differ in insulation voltage or channel configuration.
