Overview
The PS2501-2XGRG is a dual-channel optoisolator from Isocom Components, housed in an 8-DIP package. It features transistor outputs and supports DC input. Key electrical parameters include a maximum forward current of 50 mA, a collector-emitter voltage of 80 V, and an isolation voltage of 5300 Vrms. The Current Transfer Ratio ranges from 100% to 300% at 5 mA input. Typical switching times are 4 µs rise and 3 µs fall.
Feature Summary
- Dual-channel configuration for independent signal isolation
- High isolation voltage rating for safety-critical applications
- Transistor output type for digital signal interfacing
Applications
- Industrial control systems requiring galvanic isolation
- Microcontroller interface circuits
- Power supply feedback loops
Procurement Notes
Verify the specific suffix GRG against official Isocom documentation to confirm tape-and-reel packaging and RoHS compliance status. Ensure the part number matches the exact pinout and electrical specifications required for your design. Cross-reference with authorized distributors to confirm availability and authenticity before procurement.
Selection Notes
Select this component when dual-channel isolation is required within a standard DIP footprint. Consider the 5300 Vrms isolation rating for high-voltage separation needs. Verify that the transistor output type aligns with the receiving circuit's input requirements. Check the CTR range to ensure sufficient gain for the application logic levels.
Part Context
This device belongs to the PS2501 series of high-density mounting phototransistor optically coupled isolators. The series offers multiple channel options and package styles. The PS2501-2 variant specifically provides two isolated channels in a compact form factor suitable for PCB space-constrained designs.
Replacement Considerations
Check for direct substitutes within the PS2501 family or equivalent dual-channel transistor output optocouplers from other manufacturers. Ensure compatibility regarding isolation voltage, pinout, and package dimensions. Verify that alternative parts meet the same electrical performance criteria.
