Working Principle

The PS2503-1-M-A is a transistor output opto-isolator that consists of a phototransistor mounted in an LED package. The device is designed to provide an electrical isolation barrier between the input and output circuits, while providing a reliable, low-cost and high-speed solution. The function of the opto-isolator is to provide an opto-coupled signal transfer between a low-level input and a high-output driver stage. The opto-isolator works by using a light-emitting diode (LED) on the input side to emit light when the input signal is applied. This light is then detected by an integrated phototransistor, which in turn triggers the output signal.

The opto-isolator is a semiconductor device and can be operated using both AC and DC power sources. It features a maximum operating temperature of 70°C, high-speed switching times (up to 2µs) and a minimum transfer ratio of 40%. In terms of electrical characteristics, the PS2503-1-M-A offers a very low input capacitance of 8pF, as well as an output leakage current of less than 1µA.

The PS2503-1-M-A is a reliable, cost-effective and easy to integrate isolation device that is suitable for use in a range of applications. It enables a fast, reliable electrical signal transfer between an input side and an output driver stage, while providing a high level of input/output isolation. It also features a high current drive capability of up to 50mA, making it well suited for use in a variety of high-voltage systems. Additionally, its IC-level compatibility gives it significant advantages when used in multi-level applications.
