Overview
The PS2501L-1-E3-D-A is a single-channel transistor output optocoupler manufactured by CEL. It integrates a Gallium Arsenide (GaAs) infrared emitting diode and an NPN silicon phototransistor within a compact package. The device provides electrical isolation with a rated insulation voltage of 5000 VRMS. Key electrical parameters include a maximum collector-emitter voltage of 80V, a collector current of 50mA, and a forward current of up to 80mA. The unit operates across a temperature range of -55°C to +100°C.
Feature Summary
- High isolation voltage capability for robust signal transmission
- Integrated GaAs LED and NPN phototransistor for efficient coupling
- Wide operating temperature range suitable for industrial environments
Applications
- Industrial automation control systems
- Signal isolation in noisy electrical environments
- Power supply feedback circuits
Procurement Notes
Verify the specific suffix 'D-A' against official CEL documentation to confirm package type and tape-and-reel specifications. Ensure compatibility with existing PCB footprints and reflow soldering profiles. Confirm RoHS compliance status via the manufacturer's certificate of conformity prior to procurement.
Selection Notes
Select this component when high isolation voltage and wide temperature operation are required. Compare Current Transfer Ratio (CTR) specifications against circuit requirements. Verify that the 4-pin SMD package dimensions match the design constraints. Ensure the input forward current limits are respected in the driving circuit design.
Part Context
This part belongs to the PS2501L series of high-reliability optocouplers. The series is designed for applications requiring strong galvanic isolation between input and output circuits. The L-series typically denotes specific packaging or performance variations within the broader product family.
Replacement Considerations
Consult official substitution guides for equivalent parts from Renesas Electronics or other authorized manufacturers. Verify pinout compatibility and electrical parameter equivalence before replacing.
