Abstract

An EMC (electromagnetic compatibility) bidirectional blocking voltage protection clamp is introduced. This device addresses shortcomings in existing solutions for interface applications with narrow design window. To suppress the voltage overshoot during transient stress conditions, embedded avalanche diodes accelerate the transition of the clamp to the on-state. By embedding the avalanche-driven triggering mechanism, this device provides a fast turn-on speed without compromising its high current handling capability. The device physics insight is demonstrated via electro-Thermal numerical simulations.
