Abstract
A circuit for protecting against electrostatic discharges includes two avalanche circuit components having different turn-on delays with respect to a beginning of an electrostatic discharge. The two avalanche circuit components are coupled in parallel. The avalanche circuit component closer to an output node has a turn-on delay on the order of 30 ns, while the avalanche circuit component closer to an input node has a turn-on delay on the order of 1 ns.
