Optoisolators are electric isolators used to prevent the transfer of signals and interference from one device or circuit to another. A popular type of optoisolator is the logic output optoisolator, which uses a light emitting diode (LED) to artificially generate a logic gate, allowing isolated communication between two or more circuits or devices. Among the logic output optoisolators is the5962-9685201HYA, a type of optoisolator with a phototransistor output.

Application Field

The 5962-9685201HYA optoisolator is employed in various applications including power electronics, consumer electronics, automotive electronics, medical electronics, instrumentation, and industrial equipment. It can also be utilized in optically isolated circuits, where it facilitates the passage of a signal while keeping two or more circuits electrically isolated from one another.

Working Principle

The 5962-9685201HYA is an optoisolator with the ability to transfer electrical signals without allowing them to cross over electrically. Electrically, it utilizes a phototransistor output, which is an LED within an enclosure that is connected to the output transistor by an optically reflective shield that prevents any electron current from flowing between its terminals. This keeps the circuits electrically isolated, while the output behaves as a logic gate.

The LED portion of the 5962-9685201HYA optoisolator is connected to the input side of the circuit. This is done by first connecting the LED\'s anode to the positive voltage line and the cathode to the input of the optoisolator via a resistor. The light it emits will be optically received by the phototransistor in the 5962-9685201HYA. The light then triggers the transistor to pull current; thus, creating a logic gate on the output side of the circuit.

The 5962-9685201HYA optoisolator offers further protection since it adds a few more protection elements to the circuit, such as optically shielded isolation walls, a low on-state resistor, and a large-area LED die. This ensures that the light emitted from the LED doesn\'t cross between the circuits, leading to decreased EMI and improved reliability.

The 5962-9685201HYA also offers a higher current rating, thanks to its higher power rating of 85 mA. This makes it suitable for high power applications in which insertion loss is to be minimized. Additionally, it has a fast switch time of 5µs, allowing for faster logic restructuring once the power is removed.

Being an optoisolator with a logic output, the 5962-9685201HYA offers users further protection against electrical noise and interference, while also providing a safe and reliable way of transferring signals from one circuit to another. Its practical application in various industries makes it a popular optoisolator for logic output uses, since it enables isolated communication between circuits without risk of electrical invasion.
