TPT7742F-SO3R

Overview

The TPT7742F-SO3R is a general-purpose digital isolator manufactured by 3PEAK. It features four independent channels with a data rate of 150 Mbps and a common-mode transient immunity (CMTI) of 150 kV/µs. The device provides an isolation rating of 3750 Vrms and operates within a wide temperature range. It is housed in a 16-pin SOIC package with a width of 3.90 mm, designed for robust signal transmission across isolated boundaries.

Feature Summary

• Provides four-channel digital isolation for high-speed signal transmission
• Features high common-mode transient immunity to maintain signal integrity
• Includes safety certifications for industrial and commercial applications

Applications

• Industrial automation systems requiring galvanic isolation
• Medical equipment needing reinforced insulation barriers
• Power electronics control circuits

Procurement Notes

Verify the specific suffix 'SO3R' corresponds to the tape-and-reel packaging format required for automated assembly processes. Confirm that the 3750 Vrms isolation rating meets the safety standards applicable to your target market regulations before finalizing procurement orders.

Selection Notes

Select this component when four isolated channels are necessary for bidirectional or unidirectional data transfer. Ensure the system voltage levels match the input/output specifications. Consider the 150 Mbps data rate requirement against other family members if lower speeds suffice, or higher CMTI if extreme noise environments exist.

Part Context

This part belongs to the TPT774x series of digital isolators from 3PEAK. It shares architectural similarities with models like TPT7740 and TPT7742 but differs in channel count and specific output configurations. The series is designed to replace traditional optocouplers in modern electronic designs.

Replacement Considerations

Direct substitutes include TPT7740F-SO3R for dual-channel applications. Verify pin compatibility and isolation ratings when cross-referencing with competitor parts. Ensure the replacement maintains the same 16-SOIC footprint and thermal characteristics.
