Optoisolators are components that provide galvanic isolation, meaning that there is no physical connection between two systems. In this way, they help block high voltage surges, spikes, and other electrical noise. The EL207 is a transistor-based photovoltaic output optoisolator that is used in motor controllers and other applications.

The EL207 consists of two parts: an LED within a plastic housing and an NPN transistor. The LED emits infrared light when a voltage is applied to it, which is directed at the transistor. Electric current generated by the transistor is then output from the device. The transistor can be used to control the power of a load, such as driving a motor. The EL207 also includes a reverse-blocking diode to prevent voltage spikes.

The EL207 has a low quiescent current of 5mA, making it a good option for applications that require low power consumption. Additionally, the EL207 is highly resistant to vibration, making it suitable for applications that need to withstand harsh environmental conditions. The device also features an extended operating temperature range of -55°C to +125°C.

Due to its design, the EL207 offers greater insulation resistance than other optoisolators. It can withstand up to 1kV of continuous voltage and up to 4kV of transient voltage. This makes it suitable for use in AC line isolation and motor control applications where power surges are a common concern. The device also features a high common mode transient immunity of up to 1000V/us.

The EL207\'s SMD package allows it to be easily mounted on a prototyping board for testing and development. It has a very low profile of less than 0.1mm, making it easy to fit into tight spaces. The device also features a very long lifetime of up to 50,000 hours, ensuring reliable operation for extended periods of time.

In summary, the EL207 is an ideal optoisolator for motor control and AC line isolation applications that require a high degree of electrical isolation. The device has a low quiescent current, is highly resistant to vibration and temperature extremes, and offers superior insulation resistance. Additionally, the EL207 is available in an SMD package that makes it easy to mount and provides an extended lifetime for reliable operation.
