Description
The TPC817S1B RAG is a high-performance 1-channel phototransistor optocoupler designed for electrical isolation between input and output circuits. By using an infrared LED to optically transmit signals to a phototransistor, it prevents high-voltage spikes or electrical noise from damaging sensitive downstream components, making it an essential component for safety and noise immunity in electronics.
This device offers a high isolation voltage of 5000V rms, ensuring reliable protection in industrial and consumer applications. With a Current Transfer Ratio (CTR) ranging from 130% to 260%, it provides efficient signal coupling for various switching and control circuits. Housed in a compact 4-pin SMD package, it is ideal for modern, space-constrained PCB designs while meeting strict environmental standards like RoHS and halogen-free compliance.
