The PS2503-1 is an optoisolator, or optical coupler, belonging to the Transistor, Photovoltaic Output (TPO) category. An optoisolator provides electrical isolation between two circuits while allowing them to communicate by using light instead of sound or electrical connections. The optoisolator can be considered the one-way gate between the two circuits where the input signal on one side will cause a change in the output of the other side.

The PS2503-1 is a single channel, low current optoisolator in a 6-pin DIP package. It contains two components: an infrared LED light source and a phototransistor output. The input signal is the current flow across the LED. The required operating current range is 15mA to 25mA. The input on this optoisolator is polarity sensitive so the positive current needs to flow into the cathode of the LED while the negative current should flow into the anode. This allows the transfer of the input signal, a voltage of 4.5+0.7V or 0V, directly to the output, the phototransistor.

The phototransistor is the second component of the optoisolator. This is a type of transistor that senses and amplifies the infrared light from the LED when the input voltage is greater than the LED voltage. This turns the transistor switch on and the output is then in the “on” state. When the input is 0V, the LED switch off and the phototransistor output will remain in an “off” state. The PS2503-1 has a built-in pull-up resistor, which allows for a very high load impedance with negligible current losses.

The PS2503-1 is designed for applications that require electrical isolation at low levels of current. These can be where DC signals need to be sent through a different voltage system, such as two 5 volt circuits. The optoisolator offers isolation between the two circuits so that the voltage on one side will not cause a “short” if the other voltage is different, allowing the signal to be sent without it being affected by the voltage differences. Other applications may include ACM systems, where the optoisolator allows for higher levels of safety. It can also be used to control logic functions and as signal input / output devices.

The PS2503-1 optoisolator is a reliable and popular choice for anyone needing to transfer low current DC signals with electrical isolation. With a wide operating voltage range, it is easy to set up and use. It is a versatile device and can be implemented in many applications with a wide range of voltage requirements. With its simple design and reliability, it is an ideal choice when seeking a low cost, effective solution to transferring current.
