Description
The HSDL-4200 series of emitters are the first in a sequence of emitters that are aimed at high power, low forward voltage, and high speed. These emitters utilize the T ransparent S ubstrate, double heterojunction, Al uminum Ga l-lium A r s enide (TS AlGaAs) LED technology. These devices are optimized for speed and efficiency at emission wavelengths of 875nm. This material produces high radiant efficiency over a wide range of currents up to 500 mA peak current. The HSDL-4200series of emitters are available in a choice of viewing angles, the HSDL-4230 at 17° and the HSDL-4220 at 30°. Both lamps are packaged in clear T-13/4(5mm) packages.

Notes:
1. Derate linearly as shown in Figure 4.
2. Any pulsed operation cannot exceed the Absolute Max Peak Forward Current as specified in Figure 5.
3. The transient peak current is the maximum non-recurring peak current the device can withstand without damaging the LED die and the wire bonds.
