Optoisolators provide electrical isolation between input and output circuits by utilizing a light transmissive barrier between them. This is particularly useful in applications that require stringent safety standards, stringent electrical noise reduction, or high reliability. The CNY17F2SVM is a surface mount photovoltaic output, 5-pin optoisolator, which offers superior EMI and ESD protection in an industry standard SOP package. It is optimized for high surge and ESD protection in industrial applications, such as instrumentation, data communications, automotive and medical devices.

Application Fields

The CNY17F2SVM optoisolator is ideal for use in industrial applications that require superior EMI and ESD protection. It has the ability to operate in high-temperature environments (up to 110°C) and has high immunity to EMI, making it suitable for use in many types of electronic systems, including automotive and medical electronics. It is also ideal for use in instrumentation and data communication applications, as its low-power consumption and low voltage drop (14V) are beneficial in conserving energy and maintaining signal integrity. Furthermore, its high isolation voltage of 2800Vrms makes it suitable for use in enhanced safety applications, such as machinery controllers.

Working Principle

The CNY17F2SVM optoisolator uses a 5-pin device to transfer digital signaling. Its internal photodiode captures the light energy emitted by the LED and converts electrical energy to a photocurrent that is then delivered to the output transistor. This photocurrent is proportional to the current that is pumped through the LED, and therefore the transferred signal is proportional to the input current. This optoisolator’s ability to transfer a digital signal without physical contact between the input and output circuits has several benefits, such as enhanced safety, high reliability, and ensuring signal accuracy and noise-free transmissions.

Due to its superior EMI and ESD compliance, the CNY17F2SVM optoisolator offers increased protection to sensitive data transmissions, while its low-power consumption and flat voltage drop make it an excellent choice for energy efficiency and signal consistency. It is available in a small SOP package, making it well-suited for surface-mount designs. Additionally, it can operate up to 110°C, which makes it suitable for use in many temperature-sensitive applications.
