DESCRIPTION The QRE00034 reflective object sensor consists of an infrared emitting diode and an NPN phototransistor mounted side by side on a converging optical axis in a black housing. The phototransistor responds to radiation from the emitting diode only when a reflective object passes in its field of view. FEATURES • Phototransistor output • No contact surface sensing • Daylight filter on the sensor • Emitter = 940 nm 2001 Fairchild Semiconductor Corporation DS300254 9/21/01 1 OF 6 www.fairchildsemi.com REFLECTIVE OBJECT SENSOR QRE00034 ABSOLUTE MAXIMUM RATINGS (TA = 25°C unless otherwise specified) Symbol Rating Operating Temperature Parameter TOPR -40 to +85 Units °C Storage Temperature TSTG -40 to +85 °C Soldering Temperature (Iron)(2,3,4) TSOL-I 240 for 5 sec °C (Flow)(2,3) TSOL-F 260 for 10 sec °C IF 50 mA Reverse Voltage VR 5 V Peak Forward Current IFP 1 A Power Dissipation(1) PD 100 mW VCEO 30 V PD 100 mW Soldering Temperature EMITTER Continuous Forward Current SENSOR Collector-Emitter Voltage Power Dissipation(1) ELECTRICAL / OPTICAL CHARACTERISTICS PARAMETER (TA = 25°C) TEST CONDITIONS SYMBOL MIN TYP MAX UNITS IF = 20 mA VF — — 1.7 V VR = 5 V IR — — 100 µA — 940 — nm — — 100 nA — 880 — nm EMITTER Forward Voltage Reverse Current Peak Emission Wavelength IF = 20 mA PE SENSOR Dark Current Peak Sensitivity Wavelength VCE = 10 V, IF = 0 mA ID VCE = 5 V PS COUPLED Collector Current Collector Emitter IF = 20 mA, VCE = 10 V(6,7) IC(ON) 0.16 — 2.00 mA IF = 20 mA, IC = 0.5 mA VCE (SAT) — — 0.4 V tr — 10 — µs tf — 50 — µs Saturation Voltage Rise Time Fall Time VCE = 5 V, RL = 100 IC(ON) = 5 mA NOTES 1.
