The PS9122-F3-N-AX optoisolator is a type of device that allows for the transmission of current from one part of a circuit to another, without allowing the voltages of the two sections to mix. This is commonly used in applications that require logic level, low voltage isolation and EMI suppression. The device pairs an infrared light source with phototransistor detection to provide electrical isolation between the two parts of a circuit.

The PS9122-F3-N-AX device is primarily used in automotive, high-end telecommunications, industrial, and medical applications to provide high voltage isolation, EMI/RFI suppression, and logic level isolation. The device has a dual channel, 2.8mm compact ISO package ideal for high-density mounting applications. It has an 8-bit data transmission rate with linear logic level outputs from 7V to 200V. The operating temperature range is from -40 to +125 °C.

The optoisolator isolates signals both conservatively and effectively. A mounted LED source, activated by the input logic, produces an infrared signal that is received by the phototransistor in the same package. The output signal is set by a different voltage to ensure day and night operation. The devices can also be used to provide an additional layer of protection and insulation for microprocessors and other sensitive integrated circuits.

The optoisolator’s drive voltage is kept low-level for optimum life. The device’s linear monotonically increasing and decreasing square wave signal is a major factor in its superior performance. This gives the device the ability to provide a steady output, while running on a low voltage supply. The device also features a high noise reduction level, which is advantageous when signals need to be clearly transmitted.

The PS9122-F3-N-AX optoisolator is a robust, reliable, and cost-effective component. Its EMI suppression allows for a noise-free connection to be established between the two parts of a circuit that would otherwise be vulnerable to external interference. Additionally, the optoisolator offers a safe way to achieve current isolation without negatively affecting the performance of the circuit. Overall, it is an ideal choice for applications that require a logic level, low-voltage isolation.
