Electrical Characteristics at 350mA, Junction Temperature, T
Philips Lumileds maintains a tolerance of ± 0.06V on forward voltage measurements.
Dynamic resistance is the inverse of the slope in linear forward voltage model for LEDs. See Figures 3a and 3b.
Measured between 25°C ≤ T
Proper current derating must be observed to maintain junction temperature below the maximum. For more information,
consult the LUXEON Design Guide, available upon request.
LEDs are not designed to be driven in reverse bias. Please consult Philips Lumileds application brief AB11 for
further information.
Measured at leads, during lead soldering and slug attach, body temperature must not exceed 120°C. LUXEON emitters
cannot be soldered by general IR or Vaporphase reflow, nor by wave soldering. Lead soldering is limited to selective
heating of the leads, such as by hotbar reflow, fiber focussed IR, or hand soldering. The package back plane (slug) may
not be attached by soldering, but rather with a thermally conductive adhesive. Electrical insulation between the slug and
the board is required. Please consult Philips Lumileds Application Brief AB10 on LUXEON Emitter Assembly Information for
further details on assembly methods.
Allowable MCPCB temperature to avoid exceeding maximum junction temperature at maximum V
resistance of Star assembly.
A reduction in maximum storage and operating temperature is required due to the acrylic optic.
