TPT7721F-SOAR

Overview

The TPT7721F-SOAR is a general-purpose dual-channel digital isolator manufactured by 3PEAK. It features a 5000Vrms isolation rating and supports data rates up to 150Mbps. The device provides a common-mode transient immunity (CMTI) of 150kV/µs. It is housed in an 8-SOIC package with a width of 7.50mm.

Feature Summary

• Dual-channel enhanced digital isolation architecture
• High-speed signal transmission capability
• Robust common-mode transient immunity

Applications

• General purpose digital isolation
• Industrial communication interfaces
• Power supply control circuits

Procurement Notes

Verify the specific suffix 'SOAR' corresponds to the required tape-and-reel packaging format and temperature grade. Confirm that the 8-SOIC footprint matches the PCB layout constraints. Ensure the 5000Vrms isolation rating meets the safety requirements for the target application environment.

Selection Notes

Select this component when dual-channel isolation is required with high CMTI performance. Compare against single-channel alternatives if only one isolated path is needed. Consider the 150Mbps speed limit for high-frequency applications. Verify compatibility with the system voltage levels on both sides of the isolation barrier.

Part Context

This part belongs to the TPT772x series of high-performance dual-channel enhanced digital isolators from 3PEAK. The series offers various isolation ratings depending on the package type, with the WSOP8 and WSOP16 packages supporting 5000-VRMS ratings. The TPT7721F-SOAR specifically utilizes the SOP8 package configuration within this family.

Replacement Considerations

Check for direct pin-compatible substitutes within the TPT772x series or other 3PEAK digital isolator families. Verify that any replacement maintains the 5000Vrms isolation rating and 150Mbps data rate specifications.
