The LED55BF/LED55CF/LED56F series are 940nm LEDs in a wide angle, TO-46 package.
The LED55BF, LED55CF, and LED56F are 940 nm GaAs infrared LEDs offered in a wide‑angle TO‑46 package. The package dimensions and mechanical features are listed, and the devices are hermetically sealed and wavelength‑matched to the TO‑18 series phototransistor.
Electrical and optical characteristics include absolute maximum ratings, continuous forward current, forward voltage, reverse voltage, power dissipation, and typical performance curves such as power output versus current and temperature. Recommended soldering practices and cleaning agents are also provided.
Methanol or isopropyl alcohols are recommended as cleaning agents.
