Overview
The PS2501L-1-F3-K-A is a single-channel transistor output optocoupler manufactured by Renesas Electronics Corporation. It features an internal GaAs infrared LED coupled to an NPN phototransistor, providing electrical isolation with a rated voltage of 5000Vrms. The device utilizes a 4-pin DIP (PDIP) gull-wing package for surface or through-hole mounting. Key electrical parameters include a maximum collector-emitter voltage of 80V, a DC forward current limit of 80mA, and a typical saturation voltage of 300mV. The unit operates within a temperature range of -55°C to +100°C.
Feature Summary
- Provides high-voltage electrical isolation between input and output circuits using optical coupling technology.
- Integrates an NPN phototransistor output stage suitable for digital signal transmission and switching applications.
- Constructed with a GaAs light emitting diode to ensure reliable performance across extended industrial temperature ranges.
Applications
- Industrial control systems requiring galvanic isolation
- Measurement and testing equipment interfaces
- Power supply feedback loops
Procurement Notes
Verify the specific suffix K-A against the official Renesas datasheet to confirm packaging and tape-and-reel specifications. Confirm that the component status remains acceptable for your design lifecycle, as this series may be subject to change notices. Ensure compatibility with standard DIP-4 footprints during PCB layout validation.
Selection Notes
Select this component when a single isolated channel with NPN output is required. Compare the 80V collector-emitter rating against load requirements. Verify that the 5000Vrms isolation voltage meets safety standards for the target application environment. Consider the DIP package constraints relative to available board space.
Part Context
This part belongs to the PS2501L family of optocouplers from Renesas. The family includes variants with different channel counts and package types. The 'L' designation typically indicates a specific lead form or package style compared to the standard PS2501 series. This specific model represents a single-channel configuration optimized for general-purpose isolation tasks.
Replacement Considerations
Consult the Renesas PS2501L datasheet for direct pin-compatible alternatives within the same family. Verify that any substitute maintains the 5000Vrms isolation rating and NPN output type. Cross-reference CTR specifications to ensure signal integrity is preserved in the circuit design.
