Overview
The CEL PS2501L-1-E3-A is a single-channel transistor output optocoupler featuring an NPN silicon phototransistor and a GaAs light emitting diode. It provides 5000 Vrms isolation voltage with a maximum collector-emitter voltage of 70 V and a collector current of 30 mA. The device operates within a temperature range of -55°C to +100°C, dissipating up to 150 mW.
Feature Summary
- Optically coupled isolator containing a GaAs LED and NPN silicon phototransistor
- High insulation voltage capability for signal isolation
- Surface mount lead bending (gull-wing) package configuration
Applications
- Industrial signal isolation
- Noise suppression circuits
- Single-channel data transmission
Procurement Notes
Verify component authenticity through authorized CEL distributors or certified suppliers. Confirm the specific E3 suffix indicates lead-free compliance as per manufacturer specifications. Check current lifecycle status, as availability may be limited or subject to obsolescence notices. Ensure packaging matches surface mount requirements for automated assembly processes.
Selection Notes
Select this component when high isolation voltage is required in a compact surface mount footprint. The NPN phototransistor output suits digital switching applications. Verify thermal management capabilities against the 150 mW power dissipation limit. Consider the gull-wing package geometry for PCB layout constraints compared to standard DIP options.
Part Context
This part belongs to the PS2501 family of optocouplers manufactured by CEL. It shares core architectural similarities with the PS2501-1 and PS2501L-1 series, differing primarily in package style and regulatory compliance markings. The L-series designation typically denotes the lead-bending surface mount variant.
Replacement Considerations
Cross-reference with PS2501L-1-E3 for identical functional specifications. Verify pinout compatibility with PS2501-1 variants if transitioning from through-hole designs. Ensure substitute components maintain the 5000 Vrms isolation rating and NPN output type.
