Optical sensors are devices that sense light and transform it into an electronic signal, which can be used to measure the amount of the source. Photo detectors are one type in this category, which uses photoelectric effect to convert the light into electrical responses, so as to measure and control the corresponding energy.

TSOP75330TR is a kind of photo detector produced by TelCom Semiconductor. It is mainly applied in remote radio communication system, mainly working as remote receiver, which will detect and decode signal command and control different operations of the device. This device contains a PIN photodiode and an integrated amplifier with a Schmitt trigger to detect infrared signals up to the frequency of 30kHz. It also has a high noise immunity with its internal filter.

TSOP75330TR mainly relies on its photodiode to detect the infrared signal. The photodiode is a kind of semiconductor PN junction device, which is primarily used as a photosensitive detector. It will become conductive if it absorbs a certain amount of light energy, transforming the light signals into electric signals. The output signal of the photodiodes will be amplified and decoded by the integrated amplifier, so as to control the remote receiver operations.

TSOP75330TR also has remarkable features to protect the device, such as a built-in AGC (Auto Gain Control) circuit which keeps its sensitivity constant. It also has ESD (Electro Static Discharge) and surge protection to ensure the device keep its reliability in harsh conditions. That’s why it is widely applied in remote radio receiver operations.

In conclusion, TSOP75330TR is widely applied in radio communication systems, mainly serving as a remote receiver. It uses its photodiode to receive the infrared signals and its integrated amplifier to decode the signal commands. Moreover, it has many features to protect its reliability in harsh conditions. That’s why it is so popular in industries like home theatre receivers, air-conditioners, remote operated toys, etc.
