TPT7741-SSAR

Overview

The TPT7741-SSAR is a general-purpose digital isolator from 3PEAK, housed in a 16-pin SSOP package with a width of 0.154 inches (3.90 mm). It features four independent channels supporting data rates up to 150 Mbps. The device provides an isolation rating of 3750 Vrms and exhibits a common-mode transient immunity (CMTI) of 150 kV/µs.

Feature Summary

• Four-channel architecture for multi-signal isolation
• High-speed data transmission capability
• Robust common-mode transient immunity
• Standard surface-mount packaging

Applications

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

Procurement Notes

Verify the specific suffix SSAR against official 3PEAK documentation to confirm the exact tape-and-reel quantity and package variant. Ensure compatibility with standard 16-SSOP footprints during PCB layout. Cross-reference safety certification marks such as UL 1577 ratings directly with the manufacturer's datasheet for the specific batch to ensure regulatory compliance.

Selection Notes

Select this component when four isolated channels are required within a compact footprint. The 150 Mbps rate suits moderate-speed digital signals. Verify that the 3750 Vrms insulation level meets system safety requirements. Consider the SSOP package dimensions for thermal management and board space constraints compared to wider SOIC alternatives.

Part Context

This part belongs to the TPT774x family of high-performance digital isolators. While the broader series offers up to 5000 Vrms isolation in WSOP16 packages, the TPT7741-SSAR specifically utilizes the SOP16/QSOP16 form factor with a 3750 Vrms rating. It shares core architectural traits with other members like the TPT7740 but differs in channel configuration and package type.

Replacement Considerations

Direct substitutes include other TPT774x variants such as TPT7740 or TPT7742 if pinout compatibility allows. Check package equivalence between SSOP and QSOP types carefully. No alternative manufacturers are confirmed in the provided source material.
