PS2514L-1

The PS2514L-1 is a high-speed, single-channel phototransistor output optocoupler manufactured by Renesas Electronics Corporation. It features a GaAs infrared LED as the light source and a silicon phototransistor detector, enabling reliable electrical isolation between input and output circuits. The device offers a maximum current transfer ratio (CTR) of 100% at an input current of 5 mA, ensuring efficient signal transmission with minimal power consumption. Its compact 6-pin DIP package supports easy integration into various electronic systems while maintaining robust performance in demanding environments. Key specifications include a response time of 1.5 μs typical for fast switching applications, making it suitable for digital signal isolation in communication interfaces, microcontroller systems, and industrial control units. The optocoupler provides a high isolation voltage of up to 5000 Vrms, which protects sensitive circuitry from voltage spikes, ground loops, or transient noise. Additionally, it operates over a wide temperature range from -40°C to +85°C, enhancing its reliability in harsh conditions such as automotive, medical, and industrial automation settings. The PS2514L-1 is designed for use in applications requiring galvanic isolation, such as power supply feedback loops, motor control systems, and data line protection in telecom equipment. Its low saturation voltage and consistent CTR across temperature variations ensure stable operation under dynamic load conditions. The component also complies with RoHS standards, reflecting Renesas’ commitment to environmentally responsible manufacturing practices. This optocoupler’s internal design minimizes common-mode noise coupling, allowing it to maintain signal integrity even in electrically noisy environments. It is commonly used in isolated gate drivers, PLC I/O modules, and embedded systems where safety and signal fidelity are critical. With its proven performance, long-term stability, and compatibility with standard PCB assembly processes, the PS2514L-1 serves as a dependable solution for engineers seeking robust isolation in modern electronic designs.
