    Phototransistors

    A Phototransistor is a two-lead or three-lead semiconductor that is more sensitive than a photodiode. It senses light levels and uses them to alter currents to create an electrical signal.

    The bipolar semiconductor is can be made from silicon or another semi-conductive material.

    How do Phototransistors work?

    Once detection of light such as IR (infrared), visible light or UV (Ultraviolet) is successful, the device 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

    •Produce a higher current than photodiodes

    Where might I use a Phototransistor?

    A photo transistor can be used in many different devices and applications such as:

    • Photo interrupters

    • Industrial electronics

    • Human detection devices

    • TV

    • Air conditioning

    • Digital photo-frames

    • PCs or Laptops

    • Automatic switches (lighting equipment)

    • IP cameras

    • Security devices

    • Home electronics
