TPT7742-SOBR

Overview

The TPT7742-SOBR is a high-performance, four-channel digital isolator from the 3PEAK TPT774x series. It features a data rate of 150 Mbps and a 5 kV RMS isolation rating for the WSOP16 package. Typical static common-mode transient immunity (CMTI) is ±200 kV/µs, with dynamic CMTI at ±150 kV/µs. The device supports propagation delays up to 22 ns. It complies with UL 1577 standards for 5000 VRMS isolation.

Feature Summary

• Four-channel digital isolation architecture
• High-speed 150 Mbps data transmission capability
• Robust electromagnetic interference resistance with high CMTI ratings
• Compliant with international safety isolation standards

Applications

• Industrial automation systems requiring galvanic isolation
• Medical equipment signal isolation
• Power electronics control circuits
• Isolated communication interfaces in noisy environments

Procurement Notes

Verify the specific package variant (WSOP16 vs SOP16) as isolation ratings differ between packages. Confirm compliance requirements such as UL 1577 or VDE certification if applicable to your region. Ensure supply chain authenticity through authorized distributors. Check for RoHS compliance status before integration into regulated products.

Selection Notes

Select this component when four isolated channels are required within a single package. Choose based on the necessary isolation voltage rating; WSOP16 offers 5 kV RMS while other packages may offer lower ratings. Consider the 150 Mbps data rate requirement for high-speed applications. Evaluate power consumption specifications against system thermal constraints.

Part Context

Part of the TPT774x family of digital isolators designed for robust signal transmission across isolation barriers. The series provides multiple channel configurations and package options to suit various industrial and commercial applications requiring reliable galvanic isolation.

Replacement Considerations

Direct substitutes include other TPT774x variants with compatible pinouts and electrical characteristics. Verify channel count and isolation ratings match original design requirements. Cross-reference propagation delay and CMTI specs to ensure performance parity in existing circuit designs.
