SI8622EB-B-ISR

Digital Isolators Overview

The SI8622EB-B-ISR is a general-purpose digital isolator from the Si862x series, manufactured by Skyworks Solutions. It features two unidirectional channels with capacitive coupling isolation technology. The device supports data rates up to 150 Mb/s and offers an insulation voltage of 2500 Vrms. It operates within a supply voltage range of 2.5 V to 5.5 V and has a typical propagation delay of 8 ns. The component is housed in an 8-SOIC package and is qualified under AEC-Q100 standards for automotive applications.

Digital Isolators Feature Summary

• Utilizes capacitive coupling technology for galvanic isolation between input and output sides.
• Provides high common-mode transient immunity (CMTI) of 35 kV/µs for reliable signal transmission.
• Features a compact 8-SOIC surface-mount package suitable for space-constrained designs.

Digital Isolators Applications

• Automotive electronic control units requiring AEC-Q100 qualified components
• Industrial communication interfaces such as CAN bus and RS-485
• Power conversion systems including motor drives and inverters

Digital Isolators Procurement Notes

Verify the specific suffix 'B' indicates the correct package variant and tape/reel configuration. Confirm that the 2500 Vrms insulation rating meets the safety requirements of your application. Ensure compatibility with the required operating temperature range of -40°C to +125°C. Check for moisture sensitivity level compliance during storage and handling.

Digital Isolators Selection Notes

Select this component when bidirectional isolation is not required, as it is strictly unidirectional. Compare against the SI8622BD variant if higher insulation voltage (5000 Vrms) is needed. Consider the SI8622ED variant if a wider SOIC package is preferred for thermal or manufacturing reasons. Evaluate power consumption differences if low-power operation is critical.

Digital Isolators Part Context

This part belongs to the Si862x family of digital isolators, which are designed to replace traditional optocouplers in modern electronic systems. The family offers improved performance in terms of speed, power consumption, and size. These devices are widely used in industries demanding high reliability and robust isolation characteristics.

Digital Isolators Replacement Considerations

Direct substitutes include other Skyworks Si862x variants with matching channel count and polarity. Verify pinout compatibility before replacing with generic equivalents. Ensure the replacement maintains the same insulation voltage and CMTI specifications.
