VF - Forward Voltage (V)
Figure 10: Typical forward current vs. forward voltage @ TC = at 25°C.
Note for Figure 10:
1. Forward Voltage curve assumes that all four LED dice are connected in series.

Maximum Ambient Temperature (°C)
Figure 11: Maximum forward current vs. ambient temperature based on TJ(MAX) = 150°C.
Notes for Figure 11:
1. Maximum current assumes that all four LED dice are operating concurrently at the same current.
2. RΘJ-C [Junction to Case Thermal Resistance] for the LZ4-00G100 is typically 1.1°C/W.
3. RΘJ-A [Junction to Ambient Thermal Resistance] = RΘJ-C + RΘC-A [Case to Ambient Thermal Resistance].
