The invention relates to a method for characterising operating conditions for an electronic component permitting the sensitivity thereof to energetic interactions to be limited. The behaviour of a component subjected to a pulsed laser radiation is measured. The values of polarisation frequency and temperature (or other operating conditions) to which the component is sensitive are determined by detecting a transitory or permanent fault in the operation of the component. If necessary, the parasite currents generated are prevented from destroying the tested component at the moment of testing. A susceptibility of the component to energetic interactions and the preferred operating conditions for the component are deduced.
Procédé de caractérisation des conditions d'utilisation d'un composant électronique permettant de limiter sa sensibilité aux interactions énergétiques. On mesure le comportement d'un composant soumis à un rayonnement laser pulsé. On détermine pour quelles valeurs de polarisation, de fréquence et de température(ou autres conditions d'utilisation), ce composant y est sensible en détectant un défaut transitoire ou permanent de fonctionnement du composant. Si nécessaire, on empêche que les courants parasites produits ne détruisent, au moment de ces tests, le composant testé. On en déduit une susceptibilité du composant aux interactions énergétiques et les conditions préférables de fonctionnement de ce composant.
