Optoisolators, also known as optocouplers, are components used to provide electrical isolation between two isolated circuits, such as between two different pieces of equipment. The EL1018(TB) optoisolator is a type of optoisolator that features a transistor output and photovoltaic input. It is mainly used in applications that require electrical isolation and high isolation voltage.

The EL1018(TB) provides electrical isolation between two isolated circuits via a light-emitting diode (LED) and a transistor. When the input voltage is applied to the optoisolator’s LED, light is emitted and is then detected by a photodiode on the output side. This light causes the output side to switch, thus creating the desired electrical isolation.

The EL1018(TB) optoisolator is capable of withstanding a high isolation voltage, which is typically up to 1750Vrms. It also has a low voltage drop between the input and output sides, which helps improve the efficiency of the circuit. The device has a high response speed, with a guaranteed minimum switching speed of 1µs. The response speed and temperature range make the EL1018(TB) suitable for a wide range of applications, such as motor control, robotics, automotive, home appliances, lighting, and industrial automation.

The EL1018(TB) optoisolator is also able to provide over-voltage protection for sensitive electronic components. This is achieved by utilising a phototransistor instead of a diode, which can be used to detect and start the switch. The phototransistor also offers superior noise immunity, which helps to reduce system errors.

Finally, the EL1018(TB) optoisolator features high EMC (electro-magnetic compatibility). It is compliant with EN 55024 and EN 61000-4-2, meaning that it meets the necessary standards for safe operation. The device also offers excellent protection against static discharge, further increasing system reliability.

In summary, the EL1018(TB) optoisolator is a transistor-output, photovoltaic-input optoisolator that is used for providing electrical isolation between two isolated circuits. It features a high isolation voltage, low voltage drop, high response speed, over-voltage protection, superior noise immunity, and high EMC. The device is suitable for a wide range of applications and is suitable for providing safe operation in challenging environments.
