Overview
The PS2502-4SMT&R is a surface-mount optocoupler from Isocom Components, featuring four channels of NPN silicon Darlington phototransistor outputs driven by GaAs infrared LEDs. It provides high isolation voltage and high current transfer ratio for signal transmission between isolated circuits. The device utilizes a lead-bending Gull-wing package suitable for automated assembly.
Feature Summary
- Contains four independent optical channels with NPN Darlington transistor outputs
- Provides high electrical isolation between input and output sides
- Utilizes GaAs infrared LED emitter for efficient light coupling
- Designed for surface-mount technology via Gull-wing lead configuration
Applications
- Programmable logic controllers
- Power supply units
- Telephone and fax equipment
- Factory automation systems
Procurement Notes
Verify the specific suffix SMT&R against official Isocom documentation to confirm surface-mount availability and tape-and-reel packaging specifications. Ensure the component matches the required channel count and isolation ratings for the target circuit design before procurement.
Selection Notes
Select this component when multi-channel isolation is required in a compact surface-mount form factor. Consider the Darlington output structure for higher gain applications and verify that the operating temperature range meets the environmental requirements of the end-use system.
Part Context
This part belongs to the PS2502 series of high-density mounting photodarlington optically coupled isolators. It serves as a surface-mount alternative to through-hole DIP variants, maintaining similar electrical characteristics while enabling automated PCB assembly processes for industrial and commercial electronics.
Replacement Considerations
Cross-reference with other manufacturers' quad-channel Darlington optocouplers such as the PS2502L-4 or equivalent NEC/Renesas parts. Verify pinout compatibility and isolation voltage ratings to ensure functional equivalence in existing designs.
