SI8650BB-B-IU

Digital Isolators Overview

The SI8650BB-B-IU is a five-channel digital isolator from the Si865x series, manufactured by Skyworks Solutions. It utilizes capacitive coupling technology to provide electrical isolation with a rated insulation voltage of 2500 Vrms. The device supports unidirectional data transmission at speeds up to 150 Mb/s. Key timing parameters include a propagation delay of 8 ns and rise/fall times of 4 ns. It operates within a supply voltage range of 2.375 V to 5.5 V and features an operating temperature range from -40°C to +125°C. The component is housed in a 16-pin QSOP package and holds AEC-Q100 qualification.

Digital Isolators Feature Summary

• Provides galvanic isolation between circuits using high-reliability capacitive coupling technology.
• Supports high-speed data transmission with low propagation delay for precise signal integrity.
• Features independent channels allowing flexible configuration for multi-signal isolation needs.
• Designed for robust performance across extended industrial and automotive temperature ranges.

Digital Isolators Applications

• Industrial automation systems requiring isolated sensor interfaces
• Automotive electronics meeting AEC-Q100 reliability standards
• Power conversion circuits needing gate drive isolation
• Medical equipment requiring patient safety isolation barriers

Digital Isolators Procurement Notes

Verify the specific suffix matches the required package type and thermal rating. Confirm that the AEC-Q100 qualification aligns with target application requirements. Ensure compatibility with standard surface-mount assembly processes for the QSOP-16 footprint. Check datasheet specifications for humidity sensitivity levels prior to storage and handling.

Digital Isolators Selection Notes

Choose this component when five isolated channels are required within a single package. Consider the 2500 Vrms isolation rating against system voltage requirements. Evaluate the 150 Mb/s data rate capability against signal bandwidth needs. Assess the 8 ns propagation delay for timing-sensitive applications compared to alternative technologies.

Digital Isolators Part Context

This part belongs to the Si865x family of digital isolators, which offers various channel counts and isolation voltages. The SI8650 variant specifically provides five forward channels. It serves as a replacement for traditional optocouplers in space-constrained designs. The family includes variants with different packaging options and isolation ratings.

Digital Isolators Replacement Considerations

SI8650BC-B-IS1 offers higher isolation voltage but uses SOIC packaging. SI8650EC-B-IS1 provides 3750 Vrms isolation in SOIC-Narrow format. SI8652BB-B-IU combines forward and reverse channels in the same QSOP package. Verify pinout compatibility before substitution.
