TPT7740-SSAR

Overview

The TPT7740-SSAR is a high-performance four-channel digital isolator manufactured by 3PEAK. It provides an isolation rating of 3750-Vrms per UL 1577 standards, suitable for SOP16 and QSOP16 packages. The device supports data rates up to 150 Mbps and offers a common-mode transient immunity (CMTI) of 150 kV/µs. It operates within a wide temperature range of -40°C to +125°C and features low power consumption with typical static current characteristics.

Feature Summary

• Four-channel digital isolation architecture
• High common-mode transient immunity capability
• Wide operating temperature range support
• Compliance with UL 1577 safety standards

Applications

• Industrial communication interfaces
• Automotive electronic systems
• Isolated data acquisition circuits

Procurement Notes

Verify the specific package type matches the required board layout, as the SSAR suffix indicates a specific small-outline variant. Confirm that the 3750-Vrms isolation rating meets the safety requirements of the target application environment. Ensure compatibility with the system's voltage levels and signal integrity needs before finalizing procurement decisions.

Selection Notes

Select this component when four isolated channels are required in a compact footprint. Consider the 150 Mbps data rate for high-speed serial communications. Evaluate the CMTI specification against noise environments. Compare power consumption metrics if battery-operated constraints exist. Verify thermal performance within the specified temperature range.

Part Context

This part belongs to the TPT774x series of digital isolators from 3PEAK. The series utilizes proprietary isolation IP technology designed for robust performance in noisy environments. These devices are engineered to replace traditional optocouplers in modern applications requiring higher speed and reliability.

Replacement Considerations

Check for direct pin-compatible alternatives within the same family, such as other TPT774x variants, ensuring isolation ratings and channel counts match. Verify functional equivalence regarding propagation delay and power consumption before substitution.
