THERMAL CHARACTERISTICS

Thermal Resistance, Junction−to−Case

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. Pulse Test: Pulse Width = 5 ms, Duty Cycle < 10%.
