Product Overview
15-21_T1D-CP1Q2TY_2T is an EVERLIGHT SMD mono-color LED supplied in an SMD-B package. The extracted device selection data identifies the emitted color as brilliant yellow green, the chip material as AlGaInP, and the resin color as water clear. Package dimensions are specified in millimeters, with tolerances of ±0.1 mm unless otherwise mentioned.
At IF=20 mA and Ta=25°C, the LED is specified for 28.5 to 72.0 mcd luminous intensity, 140° typical viewing angle, 575 nm typical peak wavelength, and 567.5 to 575.5 nm dominant wavelength. Electrical characteristics at the same condition include 1.75 to 2.35 V forward voltage, while reverse current is 10 μA max at VR=5 V and Ta=25°C.
Absolute maximum ratings include 25 mA forward current, 60 mA peak forward current at duty 1/10 and 1 kHz, 60 mW power dissipation, 5 V reverse voltage, and 2000 V HBM electrostatic discharge. Assembly guidance includes 260°C for 10 seconds reflow soldering, 350°C for 3 seconds hand soldering, and no more than two reflow cycles.
