TLP1033A TOSHIBA Photointerrupter Infrared LED + Photo IC TLP1033A Domestic electrical appliances such as VTRs and CD players Office equipment such as photocopiers, printers and fax machines Vending machines, bank ATMs and automatic ticket machines Position detectors The TLP1033A is a high-withstanding-voltage photo-interrupter for digital output. The device combines a high-optical-output GaAs infrared LED with a high-sensitivity, high-gain Si photo-IC. The photo-IC, which supports a wide range of systems (3.3 V to 12 V), enables the device to consume less power than conventional devices. The device also features a narrow slit width and high resolution. The short lead package allows automatic mounting. · Designed for direct mounting on printed circuit boards (positioning pins included) · The short lead package allows automatic mounting TOSHIBA ― Weight: 0.6 g (typ.) : Lead length 3.4 ± 0.3 mm · Permissible board thickness: 1.6 mm or less · Gap: 5 mm · Resolution: slit width 0.5 mm · Digital output (open-collector, high-level output when no light is present) · Direct connection to logic IC · Power supply voltage: VCC = 2.7 V~15 V · Switching time: tpLH = 15 µs (max) · Detector impermeable to visible light · Package material: Polybutylene-terephthalate (UL94V-0, black) Maximum Ratings (Ta = 25°C) Characteristics LED Forward current Forward current derating (Ta > 25°C) (Ta > 85°C) Rating Unit IF 50 mA DIF/°C -0.33 -2 mA/°C VR 5 V Supply voltage VCC 15 V Output voltage VO 15 V Low-level output current (Ta = Topr) IOL 16 mA Operating temperature Topr -30~95 °C Storage temperature Tstg -40~100 °C Tsol 260 °C Detector Reverse voltage Symbol Soldering temperature (5 s) (Note 1) Note 1: Soldering is performed 1.5 mm from the bottom of the package. 1 2002-09-20 TLP1033A Recommended Operating Conditions Characteristics Symbol Min Typ.

Do not immerse the entire package in the cleaning solvent. Chemical residue on the LED emitter or the photodetector inside the photo-IC case may adversely affect the optical characteristics of the device and may drastically reduce the threshold input current. The case is made of polybutylene-terephthalate. Oil or chemicals may cause the package to melt or crack. Care must be taken in relation to the environment in which the device is to be installed. Mount the device on a level surface. Output fluctuates for 100 ms after power-on while the internal circuit stabilizes. To stabilize the power line, insert a bypass capacitor of up to 0.01 mF between VCC and GND, close to the device. The threshold input current increases over time due to current flowing in the infrared LED. The design of circuits which incorporate the device must take into account the change in threshold input current over time. The change in threshold input current is equal to the reciprocal of the change in LED infrared optical output.

If the material is of inferior quality, light from the LED may pass through the shutter, causing the device to malfunction. 3 2002-09-20 TLP1033A Package Dimensions Unit: mm Product number (TL omitted) LED Country of origin Center of sensor ( ): reference value Weight: 0.6 g (typ.)
