Current Sensors Procurement Notes

This component is officially listed as End-of-Life (EOL) by the manufacturer. Verification of final stock availability through authorized distributors is essential before design finalization. Ensure compliance with RoHS standards and check for any specific handling requirements related to its moisture sensitivity level (MSL 3). Confirm that the discontinued status does not impact long-term production support needs.

Current Sensors Selection Notes

Select this part when a compact, transformer-based solution is required for unidirectional AC current sensing. The 12-QFN package offers space efficiency for dense layouts. Consider the 10A limit and ±5% accuracy against system requirements. The ratioed output simplifies ADC interfacing. Evaluate thermal performance given the 125°C upper limit and ensure the 2.7V-5.5V supply range matches the host system's voltage rails.

Current Sensors Part Context

The SI8502-C-IM belongs to the SI85xx series of isolated current sensors from Skyworks Solutions. This series is designed for applications demanding galvanic isolation and high precision in power monitoring. The C-IM suffix denotes the specific variant with the 12-QFN package and industrial temperature rating. It represents a specialized component for managing electrical flow in modern electronic systems where size and accuracy are critical constraints.

Current Sensors Replacement Considerations

As the SI8502-C-IM is marked as End-of-Life, designers must identify active substitutes. Potential replacements include other Skyworks SI85xx variants or competitive inductive current sensors from manufacturers like Vishay or Allegro MicroSystems. Verify pin compatibility, sensitivity, and package dimensions to ensure seamless integration into existing designs without significant PCB rework.
