The 17-21SYGC/S530-E1/TR8 from Everlight Electronics is a yellow-green surface-mount LED based on an AlGaInP emitting chip with a water-clear resin package. It is intended for indicators, switch backlighting, LCD backlighting, telecommunications equipment and general-purpose visual indication.
The exact E1 luminous-intensity rank provides 12mcd minimum and 17mcd typical luminous intensity at IF=20mA. Typical peak wavelength is 575nm, dominant wavelength is 573nm, and spectral radiation bandwidth is approximately 20nm.
At 20mA, forward voltage is 2.0V typical and 2.4V maximum. Absolute maximum ratings include 25mA continuous forward current, 60mA peak forward current at the specified pulsed condition, and 60mW power dissipation.
The LED provides a 140° typical viewing angle, making it suitable for wide-angle status indication and backlighting.
The device uses an 0805 / 2012 metric SMD package measuring approximately 2.0mm × 1.25mm × 1.0mm, with a cathode polarity mark for automated assembly.
The specified operating-temperature range is -40°C to +85°C, with storage from -40°C to +90°C and 2kV HBM ESD capability. The original Everlight datasheet specifies reflow soldering up to 260°C for 10 seconds.
The TR8 version is supplied on 8mm tape and a 7-inch reel, with 3000 LEDs per reel according to the Everlight device datasheet.
