TLP2361 Applications：

Signal Isolation: Optocouplers are commonly used to isolate signals between different sections of a system, especially in applications where there are different ground potentials or to protect sensitive components from high-voltage spikes.

Microcontroller Interfacing: Optocouplers can be used to interface microcontrollers with high-voltage or noisy circuits, providing a level of protection for the microcontroller.

Switching Power Supplies: Optocouplers are used in feedback loops of switching power supplies to provide isolation between the high-voltage side (primary) and low-voltage side (secondary).

Isolated Data Communication: In systems where data needs to be communicated between isolated sections, such as industrial control systems, optocouplers can be used to transmit signals without a direct electrical connection.

Motor Control: Optocouplers are used in motor control circuits to isolate the control signals from the high-power sections, preventing interference and protecting control circuitry.

Instrumentation Amplifiers: Optocouplers can be used in instrumentation amplifier circuits where high common-mode rejection is required.

Feedback Loops: Optocouplers are often employed in feedback loops of analog and digital circuits to transfer feedback signals while maintaining isolation.

Audio Equipment: In audio applications, optocouplers can be used to isolate different sections of audio processing circuits.

Medical Equipment: Optocouplers find applications in medical devices where electrical isolation is crucial for patient safety.

Switching and Pulse Transformer Replacement: Optocouplers can be used in place of traditional switching transformers or pulse transformers for signal transfer and isolation.
