76. LED Electrical Characteristics

Question.2

You’re using a Cree 5 mm Blue LED (C503B-BCN-CV0Z0461).

From the datasheet:

  • Absolute max forward current at 25 °C ambient = 30 mA.
  • The datasheet provides a derating curve showing how the max current reduces as the ambient temperature rises.

Question:
 At 85 °C ambient, what is the maximum continuous forward current the LED can safely handle?
