For the first time, the heavy-ions induced degradation and Single Event Latchup (SEL) are studied in SCR ESD protection structures for space applications. The device degradation strongly depends on the doping profile. A high SEL sensitivity is observed when the devices are used to protect high-voltage (HV) I/O pins.

Abstract
For the first time, the heavy-ions induced degradation and Single Event Latchup (SEL) are studied in SCR ESD protection structures for space applications. The device degradation strongly depends on the doping profile. A high SEL sensitivity is observed when the devices are used to protect high-voltage (HV) I/O pins.
