The CNX39U300W optoisolator is a transistor-photovoltaic output (TPO) device that is designed to provide high-temperature isolation between a low-voltage input and high-voltage output. It consists of an infrared emitters and a phototransistor. The device is in an 8-pin package with a cross-linked TPO isolation design. The part is considered a "surface-mount" device due to its small outline profile.

The CNX39U300W is a high temperature optoisolator with an operating temperature range between -40°C and 125°C. It offers an isolation voltage rating of 2500V rms and a current transfer ratio (CTR) of 100-300%. The device also offers a guaranteed TRIAC-commutated output with 5mA and DC current specs from 12mA to 20mA for phototransistor switching. The minimum off-state current (5mA) ensures good performance over a wide range of temperatures.

The CNX39U300W optoisolator is suitable for a wide range of applications, including industrial control systems, motor control systems and other applications that require high temperature operation. The device is used for AC input to DC output switching applications. It can be used to switch high voltages and currents without requiring external components such as diodes and optocouplers. The device also has increased breakdown voltage and resistance to a wide range of noise and environmental conditions.

The working principle of the CNX39U300W optoisolator is based on the ability of an infrared LED and a NPN phototransistor to transfer electric signals across an isolation barrier. The emitter of the optoisolator is an infrared LED, which produces light every time current passes through it. The phototransistor that is integrated onto the same substrate acts as a detector, which senses the light emitted by the LED and creates a small current according to the intensity of the light. This small current is then amplified and outputted to the collector of the phototransistor. This enables electric signals to be transmitted across an isolation barrier, allowing the device to be used in high voltage/high temperature applications.

The CNX39U300W is a versatile optocoupler due to its ability to operate in a wide range of temperature and noise conditions. Its high CTR enables it to be used in a variety of applications, such as AC input to DC output switching and motor control. Its surface-mount design allows for easy installation and ensures a long-lasting reliable connection. This makes the device an ideal solution for applications that require reliable high voltage/high temperature isolation.
