Overview
The PS2501-2GRG is a dual-channel optically coupled isolator manufactured by Isocom Components. It integrates a Gallium Arsenide infrared emitting diode with two NPN silicon phototransistors within an 8-pin Dual In-line Package (DIP). The device provides high-speed switching capabilities, characterized by typical rise and fall times of 4 microseconds and 3 microseconds respectively. It features a maximum forward voltage of 1.4V and supports a maximum input current of 50mA. The unit offers robust electrical isolation with a rated voltage of 5300Vrms. Operating temperatures range from -30°C to 100°C, ensuring reliability in industrial environments.
Feature Summary
- Dual-channel configuration for simultaneous signal isolation
- High-voltage insulation between input and output circuits
- Fast switching performance suitable for data transmission
- Standard DIP packaging for through-hole mounting
Applications
- Industrial control systems requiring signal isolation
- Power supply units needing feedback loop separation
- Communication equipment interface protection
- Automated machinery control logic isolation
Procurement Notes
Verify the specific suffix GRG against official Isocom documentation to confirm package type and tape/reel specifications. Ensure compliance with UL safety standards if required for end-product certification. Confirm operating temperature ranges match application requirements before ordering.
Selection Notes
Select this component when dual-channel isolation is necessary within a single package footprint. Consider the 5300Vrms isolation rating for high-noise environments. Verify that the 50mA input current limit aligns with the driving circuit capabilities. Check availability of surface mount or lead-bending variants if PCB space is constrained.
Part Context
The PS2501 series represents a family of high-density mounting phototransistor optically coupled isolators. These devices are designed to replace standard industry components while offering enhanced parameter selection. The series includes single, dual, and quad channel options in various packages to suit different isolation needs.
Replacement Considerations
Cross-reference with Renesas PS2501-2X or Isocom PS2501-2 for functional equivalence. Verify pinout compatibility and isolation voltage ratings before substitution. Ensure thermal characteristics meet system requirements.
