SI8635ET-AS2R

Digital Isolators Overview

The SI8635ET-AS2R is a general-purpose digital isolator from the Skyworks si863x series, housed in a 16-SOIC package. It features three unidirectional channels with a data rate of 150 Mb/s and operates on a supply voltage between 2.5 V and 5.5 V. The device provides 5000 Vrms isolation voltage and utilizes magnetic coupling technology. It offers a common-mode transient immunity (CMTI) of 35 kV/µs. The component supports an operating temperature range from -40°C to +125°C and includes no shutdown function.

Digital Isolators Feature Summary

• Provides galvanic isolation via magnetic coupling technology for signal transmission across isolated domains.
• Supports high-speed data communication with a maximum rate of 150 Mb/s across three independent channels.
• Ensures robust noise immunity against fast-rising transients with a specified CMTI rating.

Digital Isolators Applications

• Industrial automation systems requiring reliable signal isolation
• Medical equipment needing enhanced safety isolation barriers
• Power electronics interfaces for motor control applications

Digital Isolators Procurement Notes

Verify the specific suffix 'R' indicates reel packaging when sourcing components. Confirm that the manufacturer designation remains Skyworks Solutions Inc., as Microchip acquired the Silicon Labs portfolio including this line. Ensure the datasheet matches the exact part number to validate the 150 Mb/s speed class and 5000 Vrms isolation rating before integration into designs.

Digital Isolators Selection Notes

Select this component when three unidirectional channels are required within a single 16-pin SOIC footprint. It is suitable for applications demanding moderate data rates up to 150 Mb/s rather than gigabit speeds. Consider the 5000 Vrms isolation level for standard industrial safety requirements. The wide operating temperature range supports deployment in harsh environmental conditions without derating concerns.

Digital Isolators Part Context

This part belongs to the si863x family of digital isolators, which utilize capacitive or magnetic coupling technologies depending on the specific sub-series. The SI8635 variant specifically denotes a three-channel configuration. The ET suffix typically indicates automotive qualification or extended temperature ranges, while AS2 refers to the SOIC-16 package style.

Digital Isolators Replacement Considerations

SI8635ET-AS2 is a tube-packaged equivalent with identical electrical specifications. SI8635ET-IS2 shares similar channel counts but may differ in isolation ratings or specific feature sets; verify datasheets carefully. Parametric equivalents listed by distributors include other variants within the si863x family that match the 3-channel, 150 Mbps profile.
