Original Press Release:

Fairchild Introduces a New Miniature Surface-Mount Infrared Transmissive Switch Ideal for Non-Contact Switching Applications With Limited Space

San Jose, CA - March 24, 2003- Fairchild Semiconductor (NYSE: FCS) today announced the introduction of a new QVE00033 phototransistor infrared transmissive switch, featuring new miniature infrared sidelookers. The QVE00033 transmissive switch's small size, surface mount package, and performance make it ideal for non-contact switching applications in disk drives, card detectors, mouse and trackballs, and motor and motion controllers. In addition, optical, non-contact switching technology makes the QVE00033 more reliable, less expensive and more power efficient in many applications versus contact switches.

The QVE00033 comes in a temperature resistant black plastic housing with a compact 7.50mm by 4.05mm footprint and a 5.40 mm package height. A GaAs light emitting diode faces a silicon phototransistor across a 2mm gap with a 0.4mm aperture. The peak transmission wavelength is infrared at 940nm. Surface-mounting eliminates through-hole pins or wire leads and contributes to a lower profile. A daylight filter on the phototransistor improves immunity to ambient light. Collector current (ICON) is 100 µA min and 600 µA max, collector-to-emitter saturation voltage (VCE SAT) is 0.4V max, operating temperature (TOPR) is -55° to +100°C, and reflow soldering temperature is 240°C peak.
