High current pulse characterization of semiconductor devices
A new ESD testing system, the exponential-edge transmission line pulse system (EETLP), is presented. EETLP generates 100 ns square pulses with a variable, exponentially decaying falling edge. When applied to an ESD protection device, the pulse shape allows for capture of both the transient and …
