PS2505-1

Overview

The PS2505-1 is a single-channel optically coupled isolator manufactured by Isocom Components. It integrates an aluminum gallium arsenide (AlGaAs) light-emitting diode with an NPN silicon phototransistor. The device features AC input response capability, allowing direct connection to AC signals without external rectification. It provides high isolation voltage and is designed for applications requiring reliable signal transmission across isolated circuits.

Feature Summary

• AC input response functionality enables direct interfacing with alternating current sources
• High isolation voltage rating ensures robust electrical separation between input and output sides
• NPN silicon phototransistor output provides standard switching capabilities
• Integrated shielding minimizes ambient light interference

Applications

• Logic-to-logic isolation in noisy industrial environments
• Line receiver circuits
• Programmable current level sensors
• Motor and servo machine digital control interfaces

Procurement Notes

Verify the specific manufacturer suffix and package variant when ordering, as Isocom components often serve as replacements for legacy parts from other manufacturers. Confirm that the requested unit matches the required isolation voltage and CTR specifications for your circuit design. Check for RoHS compliance status if environmental regulations apply to your deployment.

Selection Notes

Select this component when AC input drive is required without additional rectifying components. Ensure the phototransistor collector-emitter voltage and current ratings exceed your load requirements. Consider the operating temperature range and isolation voltage needs relative to the application's safety standards.
