reverse voltage
junction temperature
esd classification (hbm)
storage temperature
operating case temperature
soldering temperature
allowable reflow cycle

notes:

1. proper current derating must be observed to maintain junction temperature below
the maxium.
2. leds are not desinged to be driven in reverse bias.
