HCPL-3700-500E Applications Field and Working Principle

Optoisolators - Transistor, Photovoltaic Outputs, such as the HCPL-3700-500E, are components used to provide increased protection from electrical shock in an environment where a digital interface separates equipment from equipment. The HCPL-3700-500E is part of a long line of optically coupled optocoupler devices manufactured by Avago Technologies for use in industrial and consumer applications.The HCPL-3700-500E optoisolator is a 6 pin single channel device which features a built-in photodiode and an open-collector output transistor. It is a 6 pin SIP (single in-line package) device with a 4-pi distance between pins. The power rating of the device is rated up to 250mW making it ideal for use in industrial applications such as component control and temperature sensing. The optoisolator’s working principle is simple. The internal photodiode detects light emitted from an external light source such as an LED. This detection triggers the output transistor which is open-collector, meaning that it can sink current from the external load. This output current is then used to drive the external load. The zener diode is in place to protect against power surges which can cause damage. The HCPL-3700-500E is a versatile optoisolator offering a variety of features that make it an invaluable tool for industrial applications including: noise immunity, low output saturation voltage, surge protection, fast response time and low dark current. These features make it an ideal optoisolator for applications such as line-powered temperature sensing, electrical motors and equipment controls, switching drives, and power supplies. The HCPL-3700-500E is also a reliable and safe option for use in consumer applications such as home entertainment systems, security systems, and air conditioning systems. In these applications, the optoisolator helps to prevent electrical shocks and damage to sensitive components by separating 28V and lower voltage sources from the circuits. The HCPL-3700-500E is a low-cost, effective and easy-to-use optoisolator for a variety of industrial and consumer applications. Its reliable features, low power consumption and surge protection make it an invaluable tool that allows designers to meet their desired requirements.
