TPT7741F-SOBR

Overview

The TPT7741F-SOBR is a general-purpose digital isolator from 3PEAK, featuring four independent channels within a 16-pin Wide SOIC (WSOP16) package. It supports data rates up to 150 Mbps and provides a common-mode transient immunity of 150 kV/µs. The device offers a 5000 Vrms isolation rating per UL 1577 standards. Designed for robust performance, it operates across a wide temperature range and includes default low output logic states.

Feature Summary

• Four-channel digital isolation architecture
• High-speed data transmission capability
• Robust common-mode transient immunity
• Safety-certified isolation ratings

Applications

• Industrial automation systems
• Medical equipment signal isolation
• Power metering applications
• Inverter control circuits

Procurement Notes

Verify the specific suffix 'SOBR' corresponds to the Wide SOIC package and default low output configuration. Confirm that the required isolation certification level matches your system's safety requirements. Ensure the operating voltage range aligns with your design specifications before procurement.

Selection Notes

Select this component when four isolated channels are required in a compact footprint. The WSOP16 package facilitates PCB layout compared to standard SOIC. Consider the 150 Mbps speed limit for high-frequency signal integrity needs. Evaluate the 150 kV/µs CMTI for noisy industrial environments.

Part Context

This part belongs to the TPT774x series of high-performance digital isolators. The series emphasizes safety and reliability, certified by VDE, UL, and CQC. These devices are designed for applications requiring galvanic isolation between different ground domains.

Replacement Considerations

Check pinout compatibility with existing designs. Verify if alternative packages like SOP16 meet space constraints while maintaining similar electrical characteristics.
