Photo Detector
E7815 consists of a photodiode and a signal processing circuit for amplifying the photocurrent generated from the photodiode up to 1400 times. Despite a small active area, E7815 provides an output nearly equal to that from photodiodes with a 20 × 20 mm active area. E7815 can be used the same way as a reverse-biased photodiode, and in most cases, it delivers a sufficient output voltage by just connecting a load resistor.
FEATURES
- Subminiature, clear plastic package
- Operation just as easy as using photodiodes
- Large output current rivaling that of a phototransistor
- Good linearity
APPLICATIONS
- Energy saving sensors for TV brightness controls, etc.
- Light dimmers for liquid crystal panels
- Various types of laser power level measurement

How a Photodiode Works
A photodiode receives light. The photodiode is a type of photo detector capable of converting light into either current or voltage, depending upon the mode of operation. The photodiode can captures variations of light intensity and pick up a signal carried by a modulated light beam.
Photodiodes are similar to regular semiconductor diodes except that they may be either exposed or packaged with a window to allow light to reach the sensitive part of the device. Many diodes designed for use specifically as a photodiode will also use a PIN junction rather than the typical PN junction.......more

The Photodiode Features
Critical performance parameters of a photodiode include:
Responsivity and Response Time
The ratio of generated photo current to incident light power, typically expressed in A/W when used in photoconductive mode.
Dark current
The current through the photodiode in the absence of light, when it is operated in photoconductive mode........more |
|
|
|
Applications
P-N photodiodes are used in similar applications to other photo detectors.
Photodiodes are used in consumer electronics devices such as compact disc players, smoke detectors, and the receivers for remote controls. Photodiodes are often used for accurate measurement of light intensity in science and industry
PIN diodes are much faster and more sensitive than ordinary p-n junction diodes, and hence are often used for optical communications and in lighting regulation.......more |
|
|
P-N vs. P-I-N photodiodes
Due to the intrinsic layer, a PIN photodiode must be reverse biased (Vr). The Vr increases the depletion region allowing a larger volume for electron-hole pair production, and reduces the capacitance thereby increasing the bandwidth
A PN photodiode is more suitable for lower light applications because it allows for unbiased operation........more |
