TPT7741-SOBR

Overview

The TPT7741-SOBR is a high-performance, single-channel digital isolator from the 3PEAK TPT774x series. It features a WSOP16 package with a 5000-VRMS isolation rating per UL 1577. The device supports data transmission rates up to 150Mbps with maximum propagation delays of 22ns for both low-to-high and high-to-low transitions. It exhibits a typical dynamic common-mode transient immunity (CMTI) of ±150kV/µs. Operating within a supply voltage range of 3.0V to 5.5V, it provides robust signal isolation for digital communication interfaces.

Feature Summary

• Provides 5000-VRMS isolation rating certified under UL 1577 standards
• Supports high-speed data transmission up to 150Mbps
• Features low propagation delay of 22ns for efficient signal integrity
• Includes high common-mode transient immunity of ±150kV/µs

Applications

• Industrial automation systems requiring galvanic isolation
• Medical equipment needing certified isolation barriers
• Power electronics control circuits
• Digital communication interface isolation

Procurement Notes

Verify the specific suffix 'SOBR' corresponds to the WSOP16 package and 5000-VRMS rating. Confirm the manufacturer is 3PEAK. Check for valid certification marks such as UL 1577 on official datasheets. Ensure compatibility with system voltage requirements of 3.0V to 5.5V before procurement.

Selection Notes

Select this component when a single-channel isolator with 150Mbps speed is required. The WSOP16 package suits space-constrained designs. Verify that the 5000-VRMS rating meets safety standards. Consider the 22ns propagation delay for timing-sensitive applications. Ensure the operating voltage range matches the system logic levels.

Part Context

Part of the TPT774x family of digital isolators. Other variants in the series offer different channel counts or lower isolation ratings like 3750-VRMS in SOP16 packages. The TPT7741 specifically denotes the single-channel configuration within this high-performance lineup designed for robust industrial and medical applications.

Replacement Considerations

Check for direct substitutes within the TPT774x series. Verify pinout compatibility if replacing with other single-channel isolators. Ensure equivalent isolation voltage and CMTI ratings are maintained for safety compliance.
