Overview
The PS2502-2XG is a dual-channel optocoupler manufactured by Isocom Components. It features an infrared LED input and Darlington transistor output, housed in an 8-pin DIP package. The device provides high isolation voltage of 5300Vrms and operates within a temperature range of -30°C to 100°C. Key electrical parameters include a maximum forward voltage of 1.4V, typical rise time of 4μs, and typical fall time of 3μs. The current transfer ratio ranges from 0.8% minimum to 6% maximum, with a maximum input current of 50mA.
Feature Summary
- Dual-channel configuration for independent signal isolation
- Darlington output stage for high gain capability
- High isolation voltage rating for safety compliance
- Wide operating temperature range for industrial environments
Applications
- Industrial control systems
- Power supply protection circuits
- Smart metering applications
- Gas detection monitoring equipment
Procurement Notes
Verify the specific suffix 'G' against official manufacturer documentation to confirm RoHS compliance status and exact pinout compatibility. Ensure the 8-pin DIP package dimensions match your PCB footprint requirements. Cross-reference the 5300Vrms isolation rating with your system's safety standards before integration.
Selection Notes
Select this component when dual-channel isolation with high output gain is required. The Darlington output structure suits applications needing significant current drive from low input signals. Verify that the 0.8% to 6% CTR range meets your circuit's logic threshold requirements under all operating temperatures.
Part Context
This part belongs to the PS2501 series family of optocouplers. Isocom Components specializes in infrared optoelectronic devices, offering alternatives to discontinued industry-standard components. The PS2502 variant specifically utilizes Darlington outputs rather than standard phototransistors found in other series members.
Replacement Considerations
PS2502-2N is a documented equivalent from California Eastern Labs featuring similar 5000V isolation and Darlington output characteristics.
