Description and Introduction

Cree 430nm Blue Surface Mount LED Lamp # Introduction to the QTLP650CBTR Optocoupler  

The QTLP650CBTR is a high-performance optocoupler designed to provide reliable electrical isolation between circuits while enabling signal transmission. This component integrates an infrared LED and a phototransistor in a compact surface-mount package, making it suitable for applications requiring noise immunity, voltage isolation, and signal conditioning.  

With a typical current transfer ratio (CTR) of 100% at an input current of 5mA, the QTLP650CBTR ensures efficient signal coupling between input and output stages. Its fast switching response time makes it ideal for digital signal isolation, feedback loops, and industrial control systems. The device operates within a wide temperature range, ensuring stability in harsh environments.  

Key features include a low forward voltage drop for the LED, minimizing power consumption, and a high isolation voltage rating, enhancing safety in high-voltage applications. The compact SMD-4 package allows for easy integration into space-constrained PCB designs.  

Common applications include power supply feedback circuits, microcontroller interfacing, and noise-sensitive signal transmission in industrial automation, medical equipment, and telecommunications. The QTLP650CBTR’s reliability and performance make it a preferred choice for engineers seeking robust isolation solutions.  

For detailed specifications, refer to the manufacturer’s datasheet to ensure proper implementation in your design.
