Figure 11: Maximum forward current vs. ambient temperature based on TJ(MAX) = 125°C.
Maximum current assumes that all four LED dice are operating concurrently at the same current.
RΘJ-C [Junction to Case Thermal Resistance] for the LZ4-00R400 is typically 1.1°C/W.
RΘJ-A [Junction to Ambient Thermal Resistance] = RΘJ-C + RΘC-A [Case to Ambient Thermal Resistance].
