Procurement Notes
Verify component authenticity through authorized distributors as the part is listed as obsolete. Confirm datasheet version PN10226EJ01V0DS matches requirements. Handle with static protection measures during storage and installation to prevent damage to the internal LED and phototransistor components.
Selection Notes
Select this component when high isolation voltage and high current transfer ratio are required in a compact package. Consider the Darlington configuration for higher gain applications. Verify compatibility with input drive currents and output load requirements before integration into circuit designs.
Part Context
The PS2502-1 belongs to the PS2502 series of multi photocouplers designed for high isolation voltage applications. It is part of NEC's (now Renesas) optocoupler lineup featuring GaAs LEDs and Darlington outputs. The series includes variants like PS2502-2 and PS2502-4 with different pin configurations.
Replacement Considerations
Check for direct substitutes from Renesas or other manufacturers offering similar Darlington output optocouplers with comparable isolation voltage ratings. Verify pinout compatibility and electrical specifications match original design requirements before substitution.
