LITEON HSDL-4230

The HSDL-4200 series emitters are among the first designed to achieve high power, low forward voltage, and high speed. These emitters utilize transparent substrate double heterostructure aluminum gallium arsenide (TS AlGaAs) LED technology. These devices are optimized for speed and efficiency at an emission wavelength of 875 nm. This material produces high radiant efficiency over a wide current range up to 500 mA peak current. The HSDL-4200 series emitters offer multiple viewing angle options: 17° for the HSDL-4230 and 30° for the HSDL-4220. Both lamps feature a clear T-1¾ (5 mm) package. The package design of these emitters is optimized for efficient heat dissipation. Copper lead frames are used to achieve superior thermal performance compared to conventional steel lead frames. The wide-angle emitter HSDL-4220 is compatible with the IrDA SIR standard and can be used with the HSDL-1000 integrated SIR transceiver.
