Overview
The PS2561DL-1Y-F3-L-A is a single-channel transistor output optocoupler manufactured by Renesas Electronics. It integrates a GaAs infrared emitting diode and an NPN silicon phototransistor within a four-pin DIP gull-wing surface-mount package. The device provides electrical isolation with a rated insulation voltage of 5000 Vrms. Key electrical parameters include a maximum collector-emitter voltage of 80 V, a maximum collector current of 50 mA, and a forward voltage of approximately 1.4 V at a forward current of 40 mA. The unit supports an operating temperature range from -55°C to +110°C.
Feature Summary
- Integrates a GaAs light emitting diode and an NPN silicon phototransistor for signal transmission
- Provides high electrical isolation capability rated at 5000 Vrms
- Designed for surface mount installation using a four-pin DIP gull-wing configuration
Applications
- Industrial control systems requiring galvanic isolation
- Measurement equipment input stages
- Power supply feedback circuits
Procurement Notes
Verify the specific suffix L-A against the manufacturer's official datasheet to confirm pinout orientation and tape-and-reel specifications. Ensure the component matches the required isolation voltage and thermal ratings for the target application environment. Cross-reference the Renesas part number with authorized distributor catalogs to confirm current availability and authenticity before procurement.
Selection Notes
Select this component when a surface-mount solution is required for single-channel isolation with high voltage withstand capabilities. Consider the 80 V collector-emitter voltage and 50 mA collector current limits to ensure compatibility with the load circuit. Verify that the 110°C maximum operating temperature meets the environmental requirements of the final assembly.
Part Context
This part belongs to the PS2561 series of transistor output optocouplers. The series includes various packages such as standard DIP and flat packages, with different isolation voltage ratings and CTR ranges. The DL variant specifically denotes the surface-mount gull-wing form factor, distinguishing it from through-hole or other SMD configurations within the broader product family.
Replacement Considerations
Consult the official Renesas replacement guide for direct equivalents. Generic replacements must match the 5000 Vrms isolation rating, NPN phototransistor output type, and DIP-4 SMD package dimensions. Verify that substitute components meet the same electrical characteristics for forward voltage, collector current, and switching times.
