Overview
The TVS0500DRVR, produced by Texas Instruments, is a 5-V Flat-Clamp Surge Protection Device designed to protect systems from high power transients and lightning strikes. This device is particularly suited for industrial signal lines and other applications requiring robust surge and ESD protection. It features a unique feedback mechanism that ensures precise flat clamping during fault events, keeping the system exposure below 10 V. This allows designers to select system components with lower voltage tolerance, reducing system costs and complexity without compromising on robustness.
