Overview
The CEL PS2501AL-1-L-A is a single-channel optically coupled isolator featuring a Gallium Arsenide (GaAs) infrared light emitting diode and an NPN silicon phototransistor. It provides electrical isolation with a voltage rating of 5000Vrms. The device utilizes a Gull-wing surface mount package for PCB integration. Key electrical characteristics include a minimum Current Transfer Ratio (CTR) of 200% and a maximum CTR of 400%, both measured at a forward current of 5mA.
Feature Summary
- Optical isolation between input GaAs LED and output NPN phototransistor
- High dielectric strength with 5000Vrms isolation voltage rating
- Surface mount Gull-wing lead configuration for automated assembly
Applications
- Industrial control systems requiring signal isolation
- Power supply feedback loops
- Microprocessor input/output interface circuits
Procurement Notes
Verify the specific suffix L-A against manufacturer documentation to confirm lead form and material compliance. Confirm availability status as distribution channels may list this part as discontinued or obsolete. Cross-reference the full part number with official datasheets to ensure compatibility with design requirements before procurement.
Selection Notes
Select this component when high isolation voltage and surface mount packaging are required. Ensure the circuit design accommodates the specified CTR range of 200% to 400% at 5mA. Verify that the Gull-wing package dimensions fit the target PCB footprint and that the operating temperature range meets system specifications.
Part Context
This part belongs to the PS2501 series of optocouplers, which typically includes DIP and surface mount variants. The AL-1 designation specifically indicates the surface mount Gull-wing package type, distinguishing it from the standard DIP versions like the PS2501A-1 within the same functional family.
Replacement Considerations
Official substitutes include parametric equivalents such as the PS2501AL-1. Verify pinout compatibility and electrical parameters against the original datasheet before substitution.
