A Unique Approach to TVS Characterization

摘要

In real-world conditions, the occurrence of a plurality of transient voltages is capable of dissipating significant power in circuit protection devices. In order to understand how Transient Voltage Suppressors, TVS, devices perform up to their rated power, techniques and equipment have been developed to characterize the effects of multiple industry-standard pulses being applied to TVS devices under controlled and monitored conditions. This study defines and demonstrates the TVS clamping voltage shifting that occurs during and immediately after transients are applied. It is envisioned that manufacturers of TVS devices, and circuit designers who use these devices, will find this information useful in increasing the level of transient voltage protection.
