Overview
The PS2501-1XLSMT&R is a single-channel optically coupled isolator manufactured by Isocom Components. It integrates an infrared emitting diode with an NPN silicon phototransistor in a surface-mount package. The device provides high isolation voltage of 5300 Vrms and a minimum current transfer ratio of 80%. It features a high collector-emitter breakdown voltage of 80V and is designed for space-efficient mounting applications requiring reliable signal transmission between systems with different potentials.
Feature Summary
- Integrates an infrared LED with an NPN silicon phototransistor for optical isolation
- Provides high isolation voltage capability for safe potential separation
- Ensures high current transfer ratio for efficient signal coupling
- Features high collector-emitter breakdown voltage for robust operation
Applications
- Computer terminals
- Industrial system controllers
- Measuring instruments
- Signal transmission between systems of different potentials and impedances
Procurement Notes
Verify the specific suffix configuration against official Isocom documentation to confirm the exact package type and reel specifications associated with the SMT&R designation. Ensure the component meets the required isolation voltage and current transfer ratio standards for the intended circuit design before procurement.
Selection Notes
Select this component when high density mounting is required alongside high isolation voltage requirements. The surface-mount format offers space efficiency compared to through-hole alternatives. Verify that the 80% minimum current transfer ratio aligns with the drive requirements of the receiving circuitry.
Part Context
This part belongs to the PS2501 series of high-density mounting phototransistor optically coupled isolators. The series typically includes variants with different lead spreads and packaging options, such as DIP and surface-mount configurations, all sharing the core architecture of an IR LED paired with an NPN phototransistor.
Replacement Considerations
Compatible substitutes include the NEC PS2501-1 and Renesas PS2501-1. Verify pinout compatibility and electrical parameter equivalence, specifically isolation voltage and current transfer ratio, before substitution.
