High Power TVS Diodes

Eaton High Power TVS Diodes deliver reliable overvoltage protection with fast response times, low clamping voltage, and high peak current capability for electronic equipment. These devices utilize silicon avalanche technology to protect critical circuits against damaging transient surges, including electrostatic discharge (ESD), electrical fast transient (EFT), and lightning strikes. The high peak power, current capability, and fast-acting response times make these diodes ideal for protecting critical circuits. Eaton High Power TVS Diodes are available in surface-mount and radial or through-hole footprints in industry-standard sizes for both ESD and high-power suppression. Typical applications include 5G, consumer, computing, energy, industrial, and medical devices.
