Transient Voltage Suppressor vs normal operating conditions Background: Transient Voltage Suppressors (TVSs) protect delicate load circuits from short- uration, high-intensity surges (electrostatic discharge, inductive kick, or lightning strike). uring normal operation the TVS acts like a large value resistance, but in the presence of a su f current it holds a constant clamping voltage. PROTECTING NORMAL 1. Load Power Supply TVS >30ΜΩ (normal) 20V max 5V 3000 Surge 3A for 500us TVS 10V (protecting) Load >300Q 20V max roblem: O Show that the power wasted by the TVS is much smaller than the power used by the load under normal conditions. ) The TVS has very little mass, absorbing more than 40 mJ of energy will overheat it. Show that the TVS will not be damaged by this 500 µs surge. (recall AE = Pat)
