Phototransistors

What is a Phototransistor?
A Phototransistor is a device that is able to sense light levels and use them to alter currents.
How do they work?
Once detection of light is successful, the phototransistor will alter a current flowing between an emitter and collector, depending on the light and level of intensity it receives.
Features and benefits:
• Reflow surface-mounting support
• Small, ultra-thin
• High sensitivity
• Electromagnetic noise resistance
• High linearity
Where might I use one?
• Photointerrupters
• Industrial electronics
• Human detection devices
• TV
• Air conditioning
• Digital photo-frames
• PCs or Laptops
• Automatic switches (lighting equipment)
• IP cameras
• Security devices
• Home electronics
