SI88620ED-ASR

Overview

The SI88620ED-ASR is a Skyworks digital isolator featuring two unidirectional channels in a 20-SOIC package. It operates on a supply voltage of 3 V to 5.5 V with a maximum current consumption of 9.5 mA. The device supports data rates up to 100 Mb/s and provides an isolation voltage of 5000 Vrms. Key electrical parameters include a propagation delay of 18 ns, rise/fall times of 2.5 ns, and pulse width distortion of 4.5 ns. It functions within a temperature range of -40°C to +125°C.

Feature Summary

• Provides high-speed signal transmission via capacitive coupling technology for reliable data integrity.
• Ensures robust electrical safety through 5000 Vrms insulation voltage between isolated sides.
• Supports wide operating voltage ranges from 3 V to 5.5 V for flexible system integration.

Applications

• Industrial process control systems requiring galvanic isolation
• Medical equipment needing high-voltage safety compliance
• Power metering applications involving high potential differences

Procurement Notes

Verify the specific suffix 'ASR' corresponds to the tape-and-reel packaging format rather than tube packaging when sourcing components. Confirm that the manufacturer's official datasheet aligns with the requested specifications, as ordering suffixes define physical attributes like reel quantity and moisture sensitivity level handling requirements.

Selection Notes

Select this component for designs requiring bidirectional data flow separation using unidirectional channels. Ensure the application environment stays within the specified -40°C to +125°C operational temperature range. Verify that the 100 Mb/s data rate meets the system's timing constraints and that the 20-SOIC footprint fits the PCB layout constraints.
