DESCRIPTION
The IRM 6000 is a slim package, fully contained Infrared transceiver that is
compatible with the IrDA 115.2 Kb/s Physical Layer Link Specification. Housed
in a single molded epoxy surface mount package this unique product lends
itself easily to automated pick and place assembly.
The state of the art BiCMOS circuitry coupled with the optoelectronic expertise
of Siemens makes for a product that outperforms its closest rival. Also incorporated in the module is a unique shutdown feature which allows for a power
down mode. This will greatly aid in lowering the quiescent current when the
module is not being used. In normal operation the shutdown pin should be held
low.
The slim package makes this device ideal for cellular telephone and PDA applications.

IR Convection Reflow Soldering
As with all optoelectronic devices, the IRM 6000 is sensitive to temperature rates of change a
nd peak temperatures during the solder process. It is not designed for any application in which
the component would be directly immersed in molten solder. Optimum performance will be
achieved with convection IR reflow soldering.
A preheat of up to 120°C for 2.5 minutes is recommended with a ramp up to soldering heat of
a maximum of 4°C/second.
The maximum peak temperature is 240°C and should not exceed 10 seconds at that temperature.
Cool down rate should not exceed 3°C/second.
