Littelfuse TVS Diode characteristics include:

Littelfuse TVS Diodes can fit a wide range of circuit protection applications but were primarily designed to protect I/O interfaces in telecommunication and industrial equipment, computers and consumer electronics. TVS Diodes are generally used to protect against electrical overstress such as those induced by lightning strikes, inductive load switching, and electro-static discharge (ESD) associated with transmission on data lines and electronic circuits. They function by limiting voltage to a certain level (referred to as a 'clamping' device) with p-n junctions that have a larger cross-sectional area than those of a normal diode, allowing them to conduct large currents to ground without sustaining damage. They can respond to overvoltage events faster than most other types of circuit protection devices, and are offered in a variety of surface mount and through-hole circuit board mounting formats.

TVS Diodes are electronic components designed to protect sensitive electronics from high-voltage transients.

View the Circuit Protection Product Selection Guide to learn more about how to select these devices and Littelfuse’s complete TVS diode offering When selecting TVS Diodes there are some important parameters to be considered, these are Reverse Standoff Voltage (VR), Peak Pulse Current (IPP) and Maximum Clamping Voltage (VC max). Littelfuse TVS diodes are available in both uni-directional (uni-polar) or bi-directional (bi-polar) diode circuit configurations. TVS Diodes are silicon avalanche devices typically chosen for their fast response time (low clamping voltage), lower capacitance and low leakage current. The Transient Voltage Suppressor diode (also known as a TVS Diode) is a protection diode designed to protect electronic circuits against transients and overvoltage threats such as EFT (electrically fast transients) and ESD (electro-static discharge). You can learn more about our range of tvs diode products by viewing our Circuit Protection Product Selection Guide. Littelfuse backs our products with over 80 years of circuit protection expertise and application knowledge developed by working with our industry-leading customers. Littelfuse offers a broad range of TVS diodes, including high peak pulse current and peak pulse power options up to 10kA and 30kW respectively.
