Overview
The PS2502L-1-F3-A is a single-channel NPN photodarlington output optocoupler from the Renesas NEPOC series. It features a GaAs LED coupled to a silicon phototransistor in a surface-mount 4-SMD gull-wing package. Key electrical parameters include a 5000 Vrms isolation voltage, a typical current transfer ratio of 2000%, and a maximum collector-emitter saturation voltage of 1 V. The device supports a maximum forward current of 80 mA and operates within a temperature range of -55°C to +100°C.
Feature Summary
- High isolation voltage capability for safe signal transmission between isolated circuits
- High current transfer ratio ensures efficient signal coupling with low input drive requirements
- Surface-mount gull-wing package design facilitates automated PCB assembly
Applications
- Industrial control systems requiring galvanic isolation
- Power supply feedback loops for voltage regulation
- Signal transmission across different ground potential domains
Procurement Notes
Verify component authenticity through authorized Renesas distributors or certified suppliers. Confirm RoHS compliance status and check for recent Product Change Notices (PCN) regarding packaging or manufacturing site updates. Ensure storage conditions meet moisture sensitivity level requirements before reflow soldering to prevent package damage.
Selection Notes
Select this component when high gain is required due to its Darlington output structure. Compare against standard phototransistor couplers if switching speed is critical, as Darlington types exhibit slower rise and fall times. Ensure the 40 V collector-emitter voltage rating meets the load requirements of the target application circuit.
Part Context
This part belongs to the PS2502L series, which offers lead-bending gull-wing packages for surface mount technology. It complements the PS2502L-1-A DIP variant and shares family characteristics such as high isolation voltage and Darlington output configuration, providing designers with flexible mounting options for similar isolation needs.
Replacement Considerations
Direct substitutes include PS2502L-1-E3, E4, F4, and PS2502L-1-L-A. Verify pinout compatibility and electrical parameter equivalence before substitution. Note that some variants may differ in tape-and-reel specifications or specific CTR ranges.
