1. Rating applies when surface mounted on the minimum pad size recommended.
2. Pulse Test: Pulse Width ≤ 300 m s, Duty Cycle ≤ 2.0%.

Maximum ratings are those values beyond which device damage can occur. Maximum ratings applied to the device are individual stress limit values (not normal operating conditions) and are not valid simultaneously. If these limits are exceeded, device functional operation is not implied, damage may occur and reliability may be affected.

1. The heat generated must be less than the thermal conductivity from Junction-to-Ambient: dP D /dT J < 1/R q JA .
