Overview
The PS2501-2XGRSM is a surface-mount optoisolator from Isocom Components, featuring two channels with transistor outputs. It provides 5300Vrms isolation voltage and supports a maximum forward current of 50mA. The device offers a minimum current transfer ratio (CTR) of 80% and a collector-emitter breakdown voltage of 80V. Designed for high-reliability applications, it operates within a temperature range of -30°C to 100°C.
Feature Summary
- Dual-channel configuration for efficient space-saving circuit design
- High isolation voltage rating ensures reliable signal transmission across potential barriers
- Transistor output structure facilitates direct interfacing with digital logic circuits
Applications
- Industrial control systems requiring galvanic isolation
- Power supply units needing feedback loop isolation
- Communication equipment signal interface protection
Procurement Notes
Verify the specific suffix GRSM against official datasheets to confirm surface-mount package dimensions and tape-and-reel specifications. Ensure compatibility with automated assembly processes by checking reel size and orientation markings. Cross-reference pinout diagrams with PCB layout requirements to prevent installation errors during manufacturing.
Selection Notes
Select this component when dual-channel isolation is required in a compact surface-mount footprint. Consider the 80% minimum CTR for robust switching performance in low-current drive scenarios. Evaluate the 5300Vrms isolation rating against system safety standards and operating voltage levels to ensure adequate margin for transient events and long-term reliability.
Part Context
This part belongs to the PS2501 series, which includes various channel counts and package options. Isocom Components manufactures these devices as replacements for legacy optocouplers, offering comparable performance with flexible manufacturing capabilities. The series is designed to meet global industry standards for optical isolation components.
Replacement Considerations
Direct substitutes include PS2501-2XSM for similar surface-mount configurations. Verify pin compatibility and electrical parameters before substitution. Alternative packages like DIP variants exist but require mechanical adaptation.
