PS2501-1SMT&R

Overview

The PS2501-1SMT&R 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 5.3 kVrms and a minimum breakdown voltage (BVCEO) of 80 V. It features a minimum current transfer ratio of 80% and supports a maximum forward input current of 60 mA. The component is designed for space-efficient mounting in compact electronic circuits.

Feature Summary

• Integrates infrared LED with NPN silicon phototransistor for signal isolation
• Provides high electrical isolation voltage rated at 5.3 kVrms
• Ensures reliable switching with a minimum current transfer ratio of 80%
• Offers high collector-emitter breakdown voltage of 80 V minimum

Applications

• Computer terminals
• Industrial system controllers
• Measuring instruments
• Signal transmission between systems of different potentials and impedances

Procurement Notes

Verify the specific suffix SMT&R confirms tape-and-reel packaging configuration against official Isocom documentation. Confirm that the part number corresponds to the standard PS2501-1 electrical specifications without custom parameter deviations. Ensure compliance with RoHS directives as indicated in manufacturer records. Cross-reference the datasheet version to validate isolation ratings and thermal characteristics prior to integration.

Selection Notes

Select this component when space-constrained designs require surface-mount technology for single-channel isolation. The high current transfer ratio ensures efficient drive requirements for downstream logic circuits. Verify that the 5.3 kVrms isolation rating meets safety standards for the target application environment. Consider the 80 V breakdown voltage capability for appropriate load switching requirements.

Part Context

This part belongs to the PS2501 series of high-density mounting phototransistor optocouplers from Isocom Components. The series includes variants with different channel counts and lead configurations. The SMT&R suffix specifically denotes the surface-mount variant supplied in tape-and-reel format for automated assembly processes.

Replacement Considerations

Compatible substitutes include PS2501-1SM for standard surface-mount packaging or PS2501-1G for 10mm lead spread options. Direct replacements from other manufacturers such as Renesas PS2501L-1Y-F3-W-A may require pinout and package dimension verification.
