Abstract :
ESD protection diodes are stressed with multiple discharges. We find a strong dependence of the maximum allowable number of stresses from the stress level. Ambient temperature and the pulse shape have an additional influence. Electrical characteristics are not altered till destruction. Physical failure analysis shows latent damage in the form of the gradual formation of a spike front that eventually shortens the junction.
