Littelfuse TVS Diode Product Selection Table
TVS Diodes are used to protect semiconductor components from high-voltage transients. Their p-n junctions have a larger cross-sectional area than those of a normal diode, allowing them to conduct large currents to ground without sustaining damage. Littelfuse supplies TVS Diodes with peak power ratings from 400W to 30kW, and reverse standoff voltages from 5V to 495V.
You can get additional TVS Diode selection guidance by visiting the TVS Diode definition and selection page by clicking here.
