Optoisolators - Transistor, Photovoltaic Output

Optoisolators are electronic components that utilize electrical isolation of two components or circuits from each other. The most common type of optocoupler is a transistor isolator, also called a photovoltaic isolator. Transistor photovoltaic isolators rely on a light-emitting diode and a photovoltaic cell to provide electrical isolation between the two components or circuits. There are a variety of transistor photovoltaic isolators available on the market, including the 6N138-X009T. This device is a high-performance, Surface Mount (SMT) optocoupler with an integrated high-gain output Transistor. It is ideal for controlling and isolating high-power, low-voltage signals in industrial, automotive, and medical equipment. The 6N138-X009T isolator is primarily designed for applications that require high noise immunity and transient protection. It can be used in both linear and switching applications, and is equipped with an integrated Synchronous Current Source that helps minimize power consumption and eliminate switching noise from the output circuit. The 6N138-X009T isolator has an operating voltage range of 5V to 35V and a load resistance range of 100 ohms to 10,000 ohms. It is also designed to operate at a fixed frequency of 10 kHz ±5%, which helps improve noise immunity. The device is capable of providing a noise immunity of over 100dB with an operating temperature range of -20°C to +105°C.The working principle of the 6N138-X009T isolator is based on the photovoltaic effect. The photovoltaic effect is a physical phenomenon in which light is converted into electric current. In the 6N138-X009T isolator, this process is made possible by an LED and a photovoltaic cell. When a voltage is applied across the LED, current is generated and the LED begins to emit light. This light is then converted into electrical current by the photovoltaic cell, which is then amplified by the Transistor. The amplified current is then passed to the output circuit. This process creates a virtual electrical barrier between the two circuits, which prevents the transmission of undesirable electrical signals or transients. Additionally, it helps reduce Electromagnetic Interference (EMI) at the isolation point. The 6N138-X009T isolator is a great solution for industrial, automotive, and medical applications that require electrical isolation and high noise immunity. With its integrated high-gain output Transistor, it is capable of providing a noise immunity of over 100 dB. Additionally, its fixed frequency design helps improve noise immunity and its temperature range helps increase reliability in extreme conditions.
