High-speed response LED for optical switches The L14337-0085R is an infrared LED developed for optical switches. It is a high-speed response LED featuring a cutoff frequency of 50 MHz (typ.). High light output Optical switches High-speed response Structure Parameter Package Reflector Window material Specification TO-46 Yes Epoxy resin Absolute maximum ratings (Ta=25 °C unless otherwise noted) Parameter Reverse voltage Forward current Forward current decrease rate Pulse forward current Pulse forward current decrease rate Power dissipation Operating temperature Storage temperature Symbol VR IF IFP P Topr Tstg *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. *2: The L14337-0085R is guaranteed to resist temperature 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. Electrical and optical characteristics (Ta=25 °C) Parameter Peak emission wavelength Spectral half width Forward voltage Reverse current Radiant flux Cutoff frequency*3 *3: Frequency at which the optical output drops by 3 dB relative to the output at 100 kHz
