Infrared LED L9337 series High power LED for optical switches The L9337 series is an infrared LED developed for optical switches. Because a high-power LED chip is mounted, the L9337 series provides higher radiant output power than previous devices, yet is available at a low cost due to the improved manufacturing process. The L9337-01/-02 use a high reliability package making them suitable for automobile applications. Features High radiant output power High reliability Low price Applications Optical switches Automobiles Absolute maximum ratings (Ta=25 °C, unless otherwise noted) Parameter Symbol Condition Reverse voltage VR Forward current IF Forward current decrease rate Ta > 25 °C Pulse width=10 μs Pulse forward current IFP Duty ratio=1% Pulse forward current Ta > 25 °C decrease rate Power dissipation P Operating temperature Topr Storage temperature Tstg *1: The L9337 is guaranteed to resist temperature cycle test of up to 5 cycles.
