Optical Sensors are devices that sense the presence of an optical signal by converting the detected optical signal into a signal that can be further utilized. Photo Detectors are a special type of Optical Sensors which are very sensitive to light and are capable of transforming light energy into electric signals. Remote Receiver applications employ some of these Photo Detectors in order to sense infrared and visible light from a remote source. The TSOP39230TR1 is one such Remote Receiver opto-coupler which utilizes a photodiode and a preamplifier to detect infrared signals in various types of remote controls.

The TSOP39230TR1 is built with a 940nm Photodiode provided at the front end of the device. The photodiode consists of a PN junction which is specially designed to receive 940nm infrared light and is coupled with a high gain preamplifier situated at the output stage. When a burst of incoming 940nm radiation hits the photodiode, the diode turns the light energy into an electrical current and the preamplifier amplifies the signal and outputs it to the other end. The TSOP39230TR1 also consists of a pair of Schottky diodes to protect the circuit from high voltage spikes.

The TSOP39230TR1 is specifically designed to detect infrared pulses from TV remotes, DVD remotes, and other types of infrared remote controls. Its compact size and low current consumption make the device an ideal choice for battery powered applications. It is also used in combination with the TSOP40K40C and the TSA5511 to construct a remote control system with high immunity to ambient light and noise. The TSOP39230TR1 can also be used to construct proximity sensing systems and occupancy sensors for intelligent home applications.

The TSOP39230TR1 has a wide thermal operating range between -40 degrees Celsius and +85 degrees Celsius, making it well suited for use in hot environments such as automobiles. The device also has a high input capacitance of 2.5pF which allows it to perform at a high speed, making it ideal for applications that require high frequency response. The detector is also immune to repetitive modulation of pulse widths, which makes it suitable for remote control applications that require different modulation patterns.

In summary, the TSOP39230TR1 is a very versatile opto-coupler suitable for a variety of applications in the Remote Receiver field. Its compact size and high frequency response make it well suited for battery powered applications in remote controls and proximity sensing systems. The device also provides high immunity to ambient light and noise, ensuring reliable performance in a variety of environments.
