3. Important Cautions & Considerations

️· Current Limiting: A critical caution states that a 25 mA maximum steady-state control current rating *must not* be exceeded. This is vital for proper device operation and preventing damage.
️· Derating: Figures 1 & 2 show typical current derating curves. This means the allowable current will decrease at higher ambient temperatures.
