SI88622ED-IS

Overview

The SI88622ED-IS is a general-purpose digital isolator from Skyworks Solutions, featuring two unidirectional channels in a 20-SOIC package. It operates on a 3 V to 5.5 V supply with a maximum data rate of 100 Mb/s and isolation voltage of 5000 Vrms. Key electrical parameters include a propagation delay of 17.5 ns typical, rise/fall times of 2.5 ns, and pulse width distortion of 4.8 ns. The device supports an operating temperature range of -40°C to +125°C and offers a minimum common-mode transient immunity of 40 kV/µs.

Feature Summary

• Provides high-speed signal transmission via capacitive coupling technology for reliable data integrity.
• Ensures safety compliance through robust 5000 Vrms insulation barrier between input and output sides.
• Delivers superior noise rejection capabilities with high common-mode transient immunity ratings.

Applications

• Industrial automation control systems
• Medical equipment signal isolation
• Power electronics gate drive circuits

Procurement Notes

Verify the specific suffix 'IS' corresponds to tube packaging rather than reel variants like 'ISR'. Confirm AEC-Q100 qualification status if automotive application is required. Check current lifecycle status as some datasheets indicate this variant may be restricted or not recommended for new designs. Ensure compatibility with SOIC-20 footprint requirements.

Selection Notes

Select this component when bidirectional isolation is not required due to its unidirectional channel configuration. Compare against SI88622EC-IS if reel packaging is preferred over tubes. Consider the SI88621BC-IS if integrated DC-DC power isolation is needed instead of external supplies. Evaluate thermal dissipation limits within the 20-SOIC package constraints.

Part Context

This part belongs to the Si8862x family of digital isolators designed for industrial applications. It utilizes Skyworks' proprietary capacitive isolation technology. The series is marketed under Industrial Isolation Solutions. It serves as a replacement for traditional optocouplers in high-speed data communication interfaces requiring galvanic isolation.
