TPT7742-SSAR

Overview

The TPT7742-SSAR is a high-performance, four-channel digital isolator manufactured by 3PEAK. It features a data rate of 150 Mbps and offers isolation ratings of 5000 VRMS for WSOP16 packages and 3750 VRMS for SOP16/QSOP16 variants per UL 1577. The device provides typical static common-mode transient immunity (CMTI) of ±150 kV/μs and dynamic CMTI of ±150 kV/μs. It operates within a wide temperature range of -40°C to +125°C and supports SOP8, WSOP8, and WSOP16 package options.

Feature Summary

• Four-channel digital isolation architecture with high-speed data transmission capabilities
• Robust electromagnetic compatibility and low radiation emissions
• Comprehensive safety certifications including VDE, UL 1577, TUV, CSA, and CQC
• High reliability suitable for automotive applications with AEC-Q100 testing

Applications

• Automotive electronic systems requiring isolated communication interfaces
• Industrial automation and control systems
• Communication infrastructure equipment
• Medical instrumentation requiring galvanic isolation

Procurement Notes

Verify the specific package suffix against the required isolation rating; WSOP16 packages support 5000 VRMS while SOP16/QSOP16 support 3750 VRMS. Confirm if the automotive-grade variant is needed for AEC-Q100 compliance. Ensure the ordering part number matches the desired pin configuration and insulation thickness specifications provided in the official datasheet.

Selection Notes

Select this component when four independent isolation channels are required for signal integrity in noisy environments. Consider the 150 Mbps data rate for high-speed digital signals. Evaluate the package type based on the required voltage isolation level and board space constraints. Verify thermal performance requirements against the specified operating temperature range.

Part Context

This device belongs to the TPT774x family of digital isolators from 3PEAK, designed for robust signal transmission across isolation barriers. The family utilizes proprietary isolation IP technology to achieve high CMTI and low power consumption. These components serve as critical interface elements in systems separating high-voltage domains from low-voltage control logic.

Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided documentation. Users should consult official 3PEAK resources or distributor databases for qualified replacements that match the specific isolation voltage, channel count, and package dimensions.
