Infrared LED L7558 series High-speed, high-power infrared LED for free space optics The L7558 series LEDs were developed for free space optical communications such as image data signal transmission, and operate at high speeds of 50 MHz. The L7558 delivers a high output of 14 mW and is used in combination with a light projection lens. The L7558-01 is sealed in a metal package capped with a glass lens that produces an angle of view of ±7° (full angle at half maximum). Both types employ a metal stem package that gives higher reliability than plastic package devices. Features Applications High-speed response: 50 MHz typ. (IF=50 mA) FSO (free space optics) High radiant output power L7558 : 14 mW typ. (IF=50 mA) L7558-01: 7 mW typ. (IF=50 mA) High reliability Absolute maximum ratings (Ta=25 °C) Parameter Forward current Reverse voltage Symbol IF VR Pulse forward current IFP Operating temperature Storage temperature Topr Tstg Condition Value 100 5 Unit mA V 1.0 A -30 to +85 -40 to +100 * °C °C Pulse width=10 μs Duty ratio=1% * 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.
