Single-Event Burnout (SEB) of bipolar junction transistors (BJTs) has been
observed nondestructively. It was revealed that all the NPN BJTs, including
small signal transistors, with thinner epitaxial layers were inherently su
sceptible to the SEE phenomenon. It was demonstrated that several design pa
rameters of BJTs were responsible for SEE susceptibility. Additionally, des
tructive and nondestructive modes of SEB were identified.
