Absolute Maximum Ratings
Stresses exceeding the absolute maximum ratings may damage the device. The device may not function or be opera-
ble above the recommended operating conditions and stressing the parts to these levels is not recommended. In addi-
tion, extended exposure to stresses above the recommended operating conditions may affect device reliability. The
absolute maximum ratings are stress ratings only. Values are at TA = 25°C unless otherwise noted.

Un datasheet est un document fourni par le constructeur du composant, où figurent toutes les données techniques sur le produit: puissance dissipée, courant maximal, tension de seuil, tension de claquage, température de stockage, etc. Ils sont en général fournis gratuitement, et se présentent très régulièrement sous la forme d'un document pdf.
