The Optoisolators - Transistor, Photovoltaic Output QTM357T1 is a 5-Pin, Mini-Flat Package Optocoupler, which is primarily used in the sensing, controlling, and indication of digital and analog signals. This optocoupler is mainly designed for bidirectional signal transport between two different circuits, which not only protects the higher level circuits but also reduces the effect of electromagnetic interference. It is highly reliable, economical, and easy to use and can be applied in a variety of field such as industrial electronics, process controls, and automotive applications.

The working principle of the QTM357T1 is based on the combination of a photovoltaic cell and a Darlington transistor output stage. A photovoltaic cell is an optically activated semiconductor device that produces a current when exposed to light of some specific wavelength. When the light source is turned on, the photovoltaic cell produces a current, which is then amplified by the Darlington transistor output stage and the amplified current is then fed to the output. This optocoupler ensures the safety and reliability of the entire system as it completely isolates the input from output which prevents the noise, malfunctioning, and interference of one circuit to another.

The QTM357T1 is mainly used in industrial autonomous cells and robotics applications, temperature control systems, smoke detectors, and sensor systems. The optocoupler is also used to protect small robot actuators, valves, and motor drives from static charges, power surges, and other interferences. It is also well suited for applications requiring large amounts of input current, such as power supplies and switches. Additionally, the optocoupler can be used for signal transmission in applications such as automotive alarm systems, TVs, VCRs, microwaves, and medical monitors.
