Overview
The PS2506L-1-A is a single-channel transistor output optocoupler manufactured by Renesas Electronics. It features an NPN Photodarlington output and operates within a temperature range of -55°C to +100°C. Key electrical parameters include a minimum current transfer ratio of 200%, a maximum collector-emitter voltage of 40 V, and a maximum collector current of 200 mA. The device provides 5000 Vrms insulation voltage and has a power dissipation rating of 300 mW. It utilizes SMD/SMT mounting in a DIP-4 Gull Wing package.
Feature Summary
- Contains a GaAs light emitting diode coupled with an NPN silicon darlington connected phototransistor for optical isolation.
- Provides high insulation voltage capability suitable for separating circuits with significant potential differences.
- Designed for through-hole or surface-mount installation using a compact four-pin configuration.
Applications
- General purpose signal isolation in industrial control systems
- Interface between microprocessors and high-voltage switching circuits
- Power supply feedback loops requiring galvanic isolation
Procurement Notes
Verify the specific suffix against official Renesas documentation to confirm pinout and packaging variations. Confirm RoHS compliance status via the manufacturer's latest datasheet. Ensure the selected variant matches the required thermal and electrical specifications for the target application environment.
Selection Notes
Select this component when a high current transfer ratio and robust isolation are required. Compare the NPN Photodarlington output characteristics against alternative transistor types if faster switching speeds are needed. Verify that the 300 mW power dissipation limit accommodates the expected operating conditions.
Part Context
This part belongs to the PS2506 series of optically coupled isolators. The series typically includes variants with different packaging options such as standard DIP and leadless configurations. The L-series designation often indicates specific lead frame or molding compound variations compared to non-L counterparts.
Replacement Considerations
Public confirmed substitute part numbers are not available in the provided source material. Consult the manufacturer's cross-reference guide for verified alternatives.
