Additional Details

The PS2603 typically consists of an LED and a phototransistor, separated by a dielectric insulation barrier. When current flows through the LED, it emits light, which activates the phototransistor, allowing current to flow through the output circuit. The insulation barrier provides the necessary electrical isolation. Key technical specifications include isolation voltage, current transfer ratio (CTR), and operating temperature range. Refer to the datasheet for precise electrical characteristics and application guidelines. This optocoupler is suitable for applications requiring isolation over a wide temperature range.
