High power LED for optical switches www.hamamatsu.com 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, moreover it 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. High radiant output power AutomobilesHigh reliability Optical switches Low price Features Applications Absolute maximum ratings (Ta=25 °C, unless otherwise noted) Parameter Symbol Condition Value Unit Reverse voltage VR 5V Forward current IF 80 mA Forward current decrease rate - Ta > 25 °C 1.1 mA/°C Pulse forward current IFP Pulse width=10 μs Duty ratio=1% 1.0 A Pulse forward current decrease rate - Ta > 25 °C 13 mA/°C Power dissipation P 150 mW Operating temperature Topr -30 to +85 °C Storage temperature Tstg -40 to +100*1 °C *1: The L9337 is guaranteed to resist temper ature cycle test of up to 5 cycles. Note: Exceeding the absolute maximum ratings even momentarily may cause a drop in product quality. Always be sure to use the product within the absolute maximum ratings.
