Is there a pin-compatible replacement for SN65220DBVR?

No pin-compatible replacements have been verified. The SN65220DBVR is a single-channel device in a 6-pin package, while most similar parts are multi-channel arrays with different pinouts.

What risks should I check before replacing SN65220DBVR?

The primary risk is pinout incompatibility, as most alternatives are multi-channel arrays. Also check the number of channels, reverse standoff voltage (Vrwm), capacitance, and ESD protection levels to ensure they meet your system's requirements.

SN65220DBVR Alternatives, Datasheet & Cross Reference | Texas Instruments

SN65220DBVR is a single-channel TVS diode from Texas Instruments in a SOT-23-6 package, designed for USB port protection. Finding a direct pin-compatible replacement is challenging due to its specific integrated function.

AI replacement insight

Package risklow

SOT-23-6 is a common package, but pinout will differ.

Electrical riskmedium

Candidates have different channel counts and capacitance; some have lower voltage ratings.

Firmware risklow

TVS diodes are passive components and do not require firmware.

Can it be replaced directly?

No direct, pin-for-pin replacement for the SN65220DBVR has been found. All candidates require engineering review and likely a board redesign.

Best replacement path

Use a functional alternative like a 4-channel TVS array (e.g., SRV05-4HTG-D) and redesign the PCB layout to use one of its channels.

Main risk

Pinout incompatibility is the main risk. The target is a 1-channel device, while all reviewed candidates are 4-channel arrays, leading to different pin functions.

Recommended alternatives

A 4-channel TVS array from a different vendor in a SOT-23-6 package with similar voltage but different pinout.
