Overview
The PS2501-1-L-A is a single-channel optically coupled isolator manufactured by Renesas Electronics Corporation. It integrates a Gallium Arsenide (GaAs) infrared emitting diode and an NPN silicon phototransistor within a four-pin DIP package. The device provides high isolation voltage of 5000Vrms between input and output circuits. Key electrical parameters include a maximum collector-emitter voltage of 80V, a DC forward current of 80mA, and a typical rise/fall time of 3µs/5µs. It operates within a temperature range of -55°C to 100°C.
Feature Summary
- Integrates a GaAs LED and NPN phototransistor for signal transmission
- Provides high insulation voltage capability for circuit isolation
- Features fast switching speed with low propagation delay
Applications
- Industrial control systems requiring galvanic isolation
- Power supply feedback loops
- Microprocessor input/output interface circuits
Procurement Notes
Verify the specific suffix 'L' against official Renesas documentation to confirm pinout and packaging variations compared to standard PS2501-1-A variants. Confirm component status as Not Recommended for New Designs (NRND) if applicable to your specific revision. Ensure compatibility with existing PCB footprints before procurement.
Selection Notes
Select this component when high isolation voltage and moderate speed are required in a through-hole DIP package. Compare CTR specifications against load requirements. Verify that the 80V collector-emitter voltage rating exceeds the maximum load voltage in the application circuit. Consider thermal dissipation limits at elevated operating temperatures.
Part Context
This part belongs to the PS2501 series of high-isolation voltage photocouplers. It shares functional similarities with the PS2501-1-A but may differ in mechanical dimensions or specific manufacturing revisions indicated by the 'L' suffix. The series is designed for general-purpose isolation in digital and analog signal transmission applications.
Replacement Considerations
Direct substitutes include PS2501-1-A and PS2501L-1-A. Verify pin compatibility and CTR ranges before substitution. Other manufacturers offer equivalent single-channel transistor-output optocouplers with similar isolation ratings.
