Introduction

HCPL-0738-500, a type of optoisolator, is an optoelectronic device popularly used in high isolation and high speed applications such as in military, aerospace and industrial applications. It has been designed for providing a high level of electrical isolation of an input and an output to ensure the accuracy of the output signal. This isolator which belongs to the Logic Output category, consists of a LED along with a fast-response surface-mounted silicon phototransistor which are both mounted inside a 6-pin Dual In Line package. Its ultra-tiny package with small creepage and clearance offerings minimizes the board space that is required.

Architecture

The HCPL-0738-500 optoisolator comprises of a mold plastic encapsulated LED along with a fast-response silicon phototransistor. It can operate at speeds up to 100Mbps, up to 24V with a peak voltage withstand of 44V. It is designed for 600W peak pulse power dissipation. Furthermore, the HCPL-0738-500 is matched with a high temperature plastic material for meeting the high level of isolation requirements. The LED element has a high current output, durability and high input sensitivity which helps it to improve the response time. The phototransistor that is equipped in the optoisolator has optimum speed and gain for general-purpose switching.

Application Fields

The HCPL-0738-500 is used in a variety of applications as it offers superior electrical characteristics, high gain, fast switching speed and a greater common-mode range. Some of the HCPL-0738-500 application fields are:

• High speed data transmission applications
• Optical data communications
• Industrial process control systems
• Motor control
• Medical systems
• Robotics
• Aircraft and missile systems

Working Principle

The working principle of the HCPL-0738-500 is similar to other optoisolators: it optically isolates the input signal from the output signal. The optoisolator consists of a light-emitting diode (LED) and a photosensitive transistor. The LED is connected to the input side of the optoisolator and generates a light beam when the input voltage is applied. The light beam is then detected by the phototransistor which is connected to the output side of the optoisolator. The phototransistor responds to the light beam by conducting electricity and producing an electrical output signal at the output side.The electrical isolation of the input and output sides of the HCPL-0738-500 is also greater than 5KV. This high level of electrical isolation prevents any voltage differences between the input and output sides and ensures the accuracy of the output signal. Furthermore, the HCPL-0738-500 has been designed with fast response times. It can offer pulse rates up to 100Mbps, ensuring quick response and accurate signal transfer even at high speeds.

Conclusion

In conclusion, the HCPL-0738-500 is a type of optoisolator which is primarily used in high isolation and high speed applications. It is designed for superior electrical characteristics, high gain, fast switching speed and greater common-mode range. The HCPL-0738-500 works by optically isolating the input signal from the output signal, thus preventing any voltage differences or interference between the two signals and ensuring accuracy of the output signal.
