Optoisolators are a type of electronic device which is designed to electrically isolate one part of a system from another part while allowing the two parts to communicate through light. The PS8501L2-E3-AX is a type of optoisolator that is composed of an infrared emitting diode optically coupled to a silicon NPN photovoltaic output transistor. This device has a number of different application fields and a specific working principle which are discussed in more detail below.

Application Fields

The PS8501L2-E3-AX is an excellent choice of optoisolator for use in a variety of application fields including:

• Digital Isolation.
• Isolated Amplifiers.
• Line Receivers.
• Data Acquisition Systems.
• Line Drivers.
• Automotive Systems.
• Medical Equipment.

The PS8501L2-E3-AX is particularly well suited for use in applications where high speed data is required, but electrical isolation is also desired. The device also has a wide operating temperature range, making it ideal for use in applications where temperature extremes must be considered.

Working Principle

The PS8501L2-E3-AX is composed of a high speed infrared emitting diode that is optically coupled to a high gain silicon NPN photovoltaic output transistor. The infrared emitting diode is used to transfer electrical energy across an insulated isolation barrier, while the output transistor amplifies and switches the signal that is received.When the device is powered on, it begins to convert the input current into light energy. This light energy is then transmitted across the isolation barrier and is detected by the output transistor which amplifies and switches the signal that was received. The signal is then used to control the system, providing electrical isolation between the two parts of the system.

Conclusion

The PS8501L2-E3-AX is an excellent choice of optoisolator for a variety of application fields. The device is composed of an infrared emitting diode which optically couples to a photovoltaic output transistor. This device is typically used to transfer current across an insulated barrier, providing electrical isolation between the two parts of the system. Thanks to its high speed data transmission capabilities and its wide operating temperature range, the PS8501L2-E3-AX is well suited for use in a variety of application fields.
