Overview
The PS2502-1-L-A is a single-channel transistor output optocoupler manufactured by Renesas Electronics. It integrates a Gallium Arsenide (GaAs) infrared emitting diode with an NPN photodarlington transistor. The device provides electrical isolation with a rated insulation voltage of 5000 Vrms. Key electrical parameters include a maximum collector-emitter voltage of 40 V, a maximum collector current of 200 mA, and a minimum current transfer ratio of 200%. The component operates within a temperature range of -55°C to +100°C and features typical rise and fall times of 100 µs.
Feature Summary
- Integrates a GaAs light emitting diode with an NPN photodarlington output for high gain
- Provides robust electrical isolation between input and output circuits
- Designed for reliable signal transmission in industrial environments
Applications
- Industrial automation control systems
- Power supply feedback loops
- Signal isolation in measurement equipment
Procurement Notes
Verify the specific suffix 'L' against the official Renesas datasheet to confirm package dimensions and marking variations. Confirm RoHS compliance status as required by project specifications. Check for end-of-life or not-recommended-for-new-designations on manufacturer channels before finalizing procurement plans.
Selection Notes
Select this component when high current transfer ratio and moderate speed are required for DC signal isolation. Ensure the 40 V collector-emitter voltage rating meets the load requirements. Verify that the 160 mA or 200 mA collector current capability aligns with the sink current needs of the destination circuit.
Part Context
This part belongs to the PS2502 series of transistor output optocouplers. The series includes variants such as PS2502-1, PS2502-4, and PS2502L-1. These devices are designed for general-purpose isolation applications requiring high reliability and standard DIP packaging options.
Replacement Considerations
Consult the official Renesas replacement guide for qualified substitutes. Cross-reference pinouts and electrical ratings with equivalent parts from other manufacturers if sourcing constraints exist.
