Infrared LED L12509 series Peak emission wavelength: 1.55 μm The L12509 series is a high-power LED that emits infrared light at a peak wavelength of 1.55 μm. The LED is suitable for applications requiring use of an infrared emitter with InGaAs photodiode. Features Application Peak emission wavelength: 1.55 μm Gas detection High radiant output power Analytical instruments TO-46 package L12509-0155L: with lens Absolute maximum ratings (Ta=25 °C, unless otherwise noted) Parameter Reverse voltage Forward current Derating rate of forward current Pulse forward current Derating rate of pulse forward current Power dissipation Operating temperature Storage temperature Soldering conditions Symbol VR IF IFP P Topr Tstg - Condition Value 1 80 Unit V mA Ta > 25 °C 1.1 mA/°C Pulse width=10 μs Duty ratio=1% 1.0 A Ta > 25 °C 13 mA/°C 150 -30 to +85 -40 to +100 260 °C or less, within 5 s, at least 1 mm away from lead roots mW °C °C - No dew condensation*1 No dew condensation*1 *1: When there is a temperature difference between a product and the surrounding area in high humidity environment, dew condensation may occur on the product surface. Dew condensation on the product may cause deterioration in characteristics and reliability. 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.
