TPT7721F-SO1R

Overview

The TPT7721F-SO1R is a dual-channel digital isolator from 3PEAK, manufactured in an SOP-8 package. It supports data rates up to 150 Mbps and provides a 3.75 kV RMS isolation rating with 9.6 kV surge capability. The device features typical ±150 kV/μs common-mode transient immunity and low power consumption of 3 mA per channel at 1 Mbps. Propagation delay is typically 12 ns, operating on a wide supply voltage range of 2.25 V to 5.5 V. It includes default low-level outputs and functions within a temperature range of -40°C to +125°C.

Feature Summary

• Provides high-speed signal transmission with 150 Mbps data rate capability
• Ensures electrical safety through 3.75 kV RMS isolation and 9.6 kV surge protection
• Maintains signal integrity under high noise environments with ±150 kV/μs CMTI
• Optimizes system efficiency via low power consumption and fast propagation delay

Applications

• Industrial automation control systems requiring galvanic isolation
• Medical equipment adhering to IEC 60601-1 safety standards
• Power electronics monitoring and gate drive circuits
• Communication interfaces needing robust ESD and surge protection

Procurement Notes

Verify the specific suffix 'F' indicates default low output state configuration as documented for the TPT7720F/TPT7721F variants. Confirm SOP-8 packaging and ensure compatibility with required isolation certifications such as VDE or UL if applicable to your design. Cross-reference official datasheets for exact pinout and thermal specifications before integration.

Selection Notes

Select this component when dual-channel isolation with high speed and low latency is required. The default low output state suits applications where a known safe state is critical upon power-up. Ensure the 2.25 V to 5.5 V supply range matches your system logic levels. Consider the SOP-8 footprint constraints and verify thermal performance within the -40°C to +125°C operating range.

Part Context

This part belongs to the TPT772x series of capacitive digital isolators by 3PEAK. It shares architectural similarities with the TPT7720 but differs in output initialization states. The series is designed for general-purpose isolation in industrial and consumer electronics, offering a balance of speed, power, and safety compliance in compact packages like SOP-8 and WSOP.

Replacement Considerations
