SI8712AC-B-IPR

Digital Isolators Overview

The SI8712AC-B-IPR is a single-channel digital isolator from Skyworks Solutions, designed as an optocoupler replacement in an 8-pin PDIP package. It utilizes capacitive coupling technology to provide electrical isolation with a rated insulation voltage of 3750 Vrms. The device supports data rates up to 15 Mb/s and features a propagation delay of 60 ns. It operates within a supply voltage range of 3 V to 30 V, consuming a typical operating current of 1.7 mA. The component is qualified under AEC-Q100 standards for automotive applications and functions reliably across an extended temperature range from -40°C to +125°C.

Digital Isolators Feature Summary

• Capacitive coupling architecture provides high-speed signal transmission with robust common-mode transient immunity.
• AEC-Q100 qualification ensures reliability and performance consistency for demanding automotive electronic environments.
• Unidirectional signal path design simplifies integration into control circuits requiring isolated feedback or monitoring.

Digital Isolators Applications

• Automotive powertrain and battery management systems
• Industrial motor drive control interfaces
• General-purpose isolated communication links

Digital Isolators Procurement Notes

Verify the specific suffix 'IPR' corresponds to the tape-and-reel packaging format required for automated assembly processes. Confirm that the AEC-Q100 qualification status meets the specific reliability requirements of the target application environment. Ensure the PDIP-8 package dimensions align with the designated footprint on the printed circuit board layout.

Digital Isolators Selection Notes

Choose this component when a unidirectional isolated channel is required with moderate data rate capabilities. The 3750 Vrms isolation rating suits applications where standard industrial isolation levels are sufficient. Consider the low quiescent current for power-sensitive designs. The automotive qualification makes it suitable for vehicle electronics where long-term stability is critical.

Digital Isolators Part Context

This part belongs to the Si8712 series of digital isolators, which are engineered to replace traditional optocouplers. The series offers advantages in size, speed, and power consumption compared to legacy LED-based isolation devices. The AC variant specifically denotes the automotive-grade qualification level, distinguishing it from commercial grade counterparts within the same functional family.

Digital Isolators Replacement Considerations

Direct pin-compatible replacements include other variants within the Si871x family, such as the SI8712AC-B-IS for SOIC-8 packaging. Verify that the alternative component maintains the same unidirectional configuration and isolation voltage ratings to ensure circuit integrity without redesigning the PCB layout.
