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 1.0 A maximum I
C
value is based upon JEDEC current gain requirements.
The 3.0 A maximum value is based upon actual current handling capability of
the device (see Figures 5 and 6).
2. Recommend use of thermal compound for lowest thermal resistance.
*Indicates JEDEC Registered Data.
