TPT7741F-SSAR

Overview

The TPT7741F-SSAR is a high-performance four-channel digital isolator manufactured by 3PEAK. It features a QSOP16 package with a 3750-Vrms isolation rating per UL 1577 standards. 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 supply voltage range of 2.25 V to 5.5 V and functions across an extended temperature range from -40°C to +125°C.

Feature Summary

• Provides four independent digital isolation channels for signal transmission
• Delivers high common-mode transient immunity for noise rejection
• Supports high-speed data communication up to 150 Mbps
• Complies with UL 1577 safety standards for reinforced insulation

Applications

• Industrial automation control systems
• Power electronics gate drive interfaces
• Medical equipment signal isolation
• Smart grid metering applications

Procurement Notes

Verify the specific suffix SSAR corresponds to the QSOP16 package and tape-and-reel delivery format as defined in the official datasheet. Confirm that the 3750-Vrms rating applies specifically to this package variant, distinct from the 5000-Vrms rating available in WSOP16 packages. Ensure compliance requirements match the intended application safety certifications.

Selection Notes

Select this component when four isolated channels are required in a compact QSOP16 footprint. It is suitable for applications demanding high CMTI and moderate data rates up to 150 Mbps. Consider the 3750-Vrms isolation limit for system design margins. Compare against TPT7740 or TPT7742 if channel directionality or pinout configurations differ from project requirements.

Part Context

This part belongs to the TPT774x family of four-channel digital isolators from 3PEAK. The family utilizes proprietary isolation IP technology to achieve high reliability and low power consumption. Variants within the family share similar electrical characteristics but differ in package types such as SOP16, WSOP16, and QSOP16, which dictate their respective isolation voltage ratings.

Replacement Considerations

Direct substitutes include other TPT774x variants like TPT7740F or TPT7742F, provided the package type and isolation rating meet the design constraints. Verify pin-to-pin compatibility and ensure the replacement maintains the required 150 Mbps data rate and 150 kV/µs CMTI performance levels.
