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
Transparent Substrate,
double
heterojunction,
Aluminum Gal-
lium
Arsenide
(TS AlGaAs) LED
technology. These devices are
optimized for speed and efficiency
at emission wavelengths of 875
nm. This material produces high
radiant efficiency over a wide
range of currents up to 500 mA
peak current. The HSDL-4200
series 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-1

The package design of these
emitters is optimized for efficient
power dissipation. Copper
leadframes are used to obtain
better thermal performance than
the traditional steel leadframes.
The wide angle emitter, HSDL-
4220, is compatible with the IrDA
SIR standard and can be used
with the HSDL-1000 integrated
SIR transceiver.

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.
