Description and Introduction

4-Pin DIP Phototransistor Output Optocoupler **Introduction to the H11A817B.300 Optocoupler**  

The H11A817B.300 is a high-performance optocoupler designed to provide reliable electrical isolation between input and output circuits. This component integrates an infrared LED and a phototransistor in a compact, industry-standard package, ensuring efficient signal transmission while maintaining galvanic isolation.  

With a minimum isolation voltage of 5,000 Vrms, the H11A817B.300 is well-suited for applications requiring robust noise immunity and protection against voltage surges. It features a high current transfer ratio (CTR) and fast switching speeds, making it ideal for use in power supplies, industrial controls, and communication systems where signal integrity is critical.  

The device operates over a wide temperature range, ensuring stability in harsh environments. Its low power consumption and dependable performance make it a preferred choice for designers seeking a cost-effective isolation solution without compromising reliability.  

Key specifications include a forward current of 60 mA for the input LED and a collector-emitter voltage of 80 V for the output transistor. The H11A817B.300 complies with relevant safety and performance standards, reinforcing its suitability for safety-critical applications.  

In summary, the H11A817B.300 optocoupler offers a balance of isolation, speed, and efficiency, making it a versatile component in modern electronic systems.
