Overview
The PS2501L-1-Q-A is a single-channel transistor output optocoupler manufactured by CEL. It features an infrared LED coupled with an NPN silicon phototransistor in a 4-SMD gull-wing package. Key electrical parameters include a 5000 Vrms isolation voltage, 80V maximum collector-emitter voltage, and 50mA output current per channel. The device operates within a temperature range of -55°C to +100°C.
Feature Summary
- Provides high-voltage electrical isolation between input and output circuits via optical transmission.
- Integrates an infrared emitting diode and an NPN phototransistor for signal coupling.
- Designed for surface mount assembly using a compact four-pin gull-wing form factor.
Applications
- Digital logic signal transmission and level shifting
- Power supply control and switching circuits
- Electrical insulation between systems and subsystems
Procurement Notes
Verify the specific suffix 'Q-A' against official datasheets to confirm qualification status or packaging variations. Confirm RoHS compliance details as required by project specifications. Check current lifecycle status, as availability may be limited. Ensure the supplier provides valid traceability documentation for the component batch.
Selection Notes
Select this component when a single-channel isolation solution with high voltage withstand capability is required. The SMD package suits automated surface mount processes. Verify that the NPN output type and 50mA drive capability meet the load requirements. Ensure the operating temperature range aligns with the environmental conditions of the target application.
Part Context
This part belongs to the PS2501L series of NEC/CEL optocouplers. The series typically includes DIP and SMD variants with similar electrical characteristics but different physical footprints. The 'L' designation often indicates a specific lead-free or enhanced specification variant within the broader product family.
Replacement Considerations
Public confirmed substitute part numbers are not available in the provided source material. Consult manufacturer cross-reference guides for equivalent components if direct substitution is necessary.
