TVS Diodes

Transient voltage suppressor (TVS) diodes defend against damage from overvoltage events by responding within picoseconds to shunt current to ground. The classic example of TVS diode use is protecting outdoor telecom equipment from lightning strikes. Littelfuse produces surface mount and leaded diodes and TVS diode arrays for that, as well as TVS diodes for cars, personal electronics, data cables, and household appliances. Consult our Circuit Protection Selection Guide to guide your search for a solution.
