DESCRIPTION The QCK3/QCK4 is a slotted opticalswitch designed for surface mount applications where extreme temperatures are experienced during solder reflow. The switch consists of a GaAs LED and a silicon photodarlington facing each other across a.157" (4.0 mm) gap. The leads are formed to sit flush on a PCB during solder reflow. FEATURES • Unique single piece housing designed to reduce cost. • High temperature housing material to withstand extreme temperature. • Shipped in plastic tubes for protection of leads and to feed automatic placement equipment. • Sensor package is infrared transparent and tinted to attenuate visible light. © 2002 Fairchild Semiconductor Corporation Page 1 of 3 5/13/02 PHOTODARLINGTON OPTICAL INTERRUPTER SWITCH QCK3 QCK4 ABSOLUTE MAXIMUM RATINGS (TA = 25°C unless otherwise specified) Parameter Symbol Rating Units Operating Temperature TOPR -55 to +100 °C Storage Temperature TSTG -40 to +85 °C Preheating Stage for 60 sec 183 °C Reflow Stage for 5 sec 230 °C 3 to 10 °C/S TSOL-F Soldering Temperature (Flow) Rate of Temperature Rise EMITTER Continuous Forward Current IF 50 mA Reverse Voltage VR 6 V PD 100 mW Collector-Emitter Voltage VCEO 30 V Emitter-Collector Voltage VECO 6 V Collector Current IC 40 mA Power Dissipation(1) PD 150 mW Power Dissipation(1) SENSOR NOTE: 1.
