TPT7720F-SO1R

Overview

The TPT7720F-SO1R is a general-purpose digital isolator from 3PEAK, designed for robust signal transmission across isolation barriers. It features a 3750Vrms isolation rating and supports data rates up to 150 Mbps. The device operates on a supply voltage range of 2.25V to 5.5V with a typical propagation delay of 12 ns. It provides high common-mode transient immunity (CMTI) of ±150 kV/µs and includes default low-level outputs. Packaged in an SOP-8 format, it ensures reliable performance in noisy environments.

Feature Summary

• High isolation voltage rating of 3750Vrms for safe barrier crossing
• Supports data transmission speeds up to 150 Mbps
• Features high common-mode transient immunity against electrical noise
• Includes default low output state for predictable initialization

Applications

• Industrial automation systems requiring galvanic isolation
• Medical equipment signal isolation
• Power electronics control circuits
• Smart metering and utility infrastructure

Procurement Notes

Verify the specific suffix SO1R corresponds to the SOP-8 tape-and-reel packaging configuration. Confirm that the 3750Vrms rating aligns with your system's safety certification requirements, such as UL or VDE standards. Ensure the default low output characteristic meets your logic interface needs without additional pull-up components.

Selection Notes

Select this component when a balance of moderate speed and high isolation voltage is required. It is suitable for applications where power consumption must be minimized while maintaining signal integrity. Consider the SOP-8 footprint constraints and verify that the 150 Mbps rate suffices for the target communication protocol. Evaluate thermal management capabilities within the operating temperature range.

Part Context

This part belongs to the TPT772x series of digital isolators from 3PEAK, which offers various channel configurations and isolation ratings. The TPT7720F variant specifically denotes a dual-channel device with default low outputs. It complements other series members like the TPT7720 and TPT7721, providing options for different isolation voltages and package types to suit diverse design architectures.

Replacement Considerations

Direct pin-to-pin replacements may include devices from other manufacturers offering similar 3750Vrms ratings and 150 Mbps speeds. Verify compatibility regarding supply voltage ranges, propagation delays, and CMTI specifications before substitution. Ensure the replacement maintains the same default output polarity and package dimensions.
