Overview
The PS2501-1XSM is a single-channel optically coupled isolator manufactured by Isocom Components. It integrates an infrared light-emitting diode with an NPN silicon phototransistor in a surface-mount package. The device provides high isolation voltage of 5300Vrms and a minimum breakdown voltage (BVCEO) of 80V. Key electrical parameters include a typical rise time of 3μs, a typical fall time of 5μs, and a maximum forward voltage of 1.4V. It operates within a temperature range of -55°C to 100°C.
Feature Summary
- High current transfer ratio for efficient signal transmission
- High isolation voltage capability for safety-critical applications
- Space-efficient surface-mount packaging design
Applications
- Computer terminal interfaces
- Industrial system controllers
- Measuring instruments
- Signal transmission between systems of different potentials
Procurement Notes
Verify the specific suffix 'XSM' against official Isocom documentation to confirm exact pinout, lead spread, and tape-and-reel specifications. Ensure compatibility with existing PCB footprints and reflow soldering profiles. Confirm UL certification status for the specific variant before integration into regulated equipment designs.
Selection Notes
Select this component for applications requiring compact surface-mount isolation with high voltage withstand capabilities. Consider the 80V collector-emitter breakdown voltage and 5300Vrms isolation rating when designing circuits involving potential differences. Verify that the single-channel configuration meets the system's channel count requirements without necessitating multi-channel alternatives.
Part Context
The PS2501 series represents a line of high-density mounting phototransistor optically coupled isolators. This specific model belongs to the PS2501 family, which is widely recognized as a standard industry replacement for legacy components. Isocom manufactures these devices to meet global safety standards, offering them as alternatives to discontinued parts from other manufacturers.
Replacement Considerations
This component serves as a direct functional replacement for NEC PS2501-1 variants. Verify pin compatibility and electrical parameter tolerances against original design specifications when substituting.
