TPT7740F-SOBR

Overview

The TPT7740F-SOBR is a high-performance, four-channel digital isolator from the TPT774x series manufactured by 3PEAK. It provides robust signal isolation with a 5000-VRMS rating per UL 1577 standards and supports data rates up to 150 Mbps. The device features a typical common-mode transient immunity (CMTI) of 150 kV/µs and operates within a supply voltage range of 2.5 V to 5.5 V. It offers a maximum propagation delay of 22 ns and functions reliably across an extended temperature range of -40°C to 125°C.

Feature Summary

• Provides four independent digital isolation channels for high-speed signal transmission
• Delivers 5000-VRMS isolation strength certified under UL 1577 standards
• Ensures high noise immunity with significant common-mode transient rejection capabilities
• Supports wide operating temperature ranges suitable for demanding industrial environments

Applications

• Industrial automation systems requiring isolated communication interfaces
• Medical equipment needing certified galvanic isolation for safety compliance
• Power electronics monitoring circuits in energy management systems
• Automotive electronic control units requiring reliable signal separation

Procurement Notes

Verify the specific suffix SOBR corresponds to the required packaging format and tape-and-reel configuration before ordering. Confirm that the 5000-VRMS UL certification meets your system's regulatory requirements. Ensure the 150 Mbps data rate aligns with your application's timing constraints. Check for any specific RoHS compliance documentation if environmental regulations apply to your deployment region.

Selection Notes

Select this component when four isolated channels are necessary for complex signal routing. The 150 Mbps speed suits applications requiring moderate to high throughput without excessive latency. Consider the WSOP16 package dimensions for PCB layout compatibility. Evaluate the 150 kV/µs CMTI against the noise environment of your target application to ensure signal integrity.

Part Context

This device belongs to the TPT774x family of digital isolators designed by 3PEAK. The series focuses on providing reliable isolation solutions for industrial and automotive sectors. The TPT7740F variant specifically offers four channels, distinguishing it from dual-channel or single-channel options within the same product line.

Replacement Considerations

Check for direct pin-to-pin replacements within the TPT774x series that may offer different isolation ratings or package options. Verify compatibility with existing circuit designs if substituting with similar isolators from other manufacturers.
