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. Pin Functions Pin no. Function Pin no.

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.
