Overview
The PS2501-2GR is a dual-channel optocoupler from the PS2501 series, manufactured by Isocom Components 2004 LTD. It features an infrared LED input and NPN phototransistor output in an 8-pin DIP package. Key electrical parameters include a maximum forward current of 50 mA, isolation voltage of 5300 Vrms, and minimum current transfer ratio of 100% at 5 mA input. The device operates within a temperature range of -30°C to +100°C, with typical rise and fall times of 4 μs and 3 μs respectively.
Feature Summary
- Dual-channel configuration for independent signal isolation
- High isolation voltage rating for safety-critical applications
- Standard DIP packaging for through-hole mounting
- Compliant with UL and VDE safety standards
Applications
- Logic-to-logic isolation in noisy environments
- Line receiver circuits
- Programmable current level sensors
- Motor and servo machine digital control interfaces
Procurement Notes
Verify the exact suffix 'GR' against official Isocom documentation to confirm tape-and-reel packaging status. Ensure the specified CTR min value matches your circuit requirements. Confirm RoHS compliance and specific lead form if required. Cross-reference with authorized distributors for genuine component sourcing.
Selection Notes
Select this part for applications requiring dual-channel isolation with high CTR. Compare with single-channel variants like PS2501-1X if only one channel is needed. Consider package size constraints and thermal management needs. Verify input current limits and output voltage ratings against system specifications.
Part Context
Part of the PS2501 series, designed as a replacement for discontinued commercial optocouplers. Isocom specializes in providing alternatives to industry-standard components with tailored parameter selections. The series includes various channel counts and output types for diverse isolation needs.
Replacement Considerations
Potential substitutes include PS2501-2X (tube) or PS2501-2XGRG (different CTR). Verify pinout compatibility and electrical characteristics before substitution. Check manufacturer datasheets for direct cross-reference recommendations.
