Overview
The PS2501AL-1-F3-H-A is a single-channel transistor output optocoupler manufactured by CEL. It features an NPN phototransistor output and a GaAs LED input, providing high isolation voltage of 5000 VRMS. Key electrical parameters include a maximum collector-emitter voltage of 70V, a collector current of 30mA, and a typical forward voltage of 1.2V. The device operates within a temperature range of -55°C to 100°C and is housed in a 4-pin DIP package.
Feature Summary
- High isolation voltage capability for safe signal transmission between isolated circuits
- NPN phototransistor output configuration for standard switching applications
- Wide operating temperature range suitable for industrial environments
Applications
- Industrial control systems requiring galvanic isolation
- Signal transmission across isolated ground potentials
- Power supply feedback loops for voltage regulation
Procurement Notes
Verify the specific suffix F3-H-A against official datasheets to confirm pinout and packaging details. Confirm availability status as distribution channels may list obsolete or limited stock items. Ensure compatibility with existing PCB footprints before procurement.
Selection Notes
Select this component when a single channel with 5000 VRMS isolation is required. Compare the 30mA collector current limit against load requirements. Verify that the 70V Vceo rating exceeds the maximum circuit voltage. Check if the DIP package fits the assembly constraints.
Part Context
This part belongs to the PS2501 series of NEC/CEL optocouplers. It is a legacy component often replaced by newer equivalents in modern designs. The series is known for reliability in general-purpose isolation tasks. Availability may be limited due to age.
Replacement Considerations
Check for direct replacements like PS2501A-1-X variants. Verify pin compatibility and electrical ratings match exactly. Consider newer generations from CEL or Renesas for improved availability.
