Overview
The PS2561AL-1-F3-L-A is a single-channel transistor output optocoupler manufactured by Renesas Electronics. It integrates an AlGaAs light-emitting diode and an NPN silicon phototransistor within a surface-mount DIP-4 package. The device provides high isolation voltage of 5000 Vrms, ensuring reliable signal transmission between isolated circuits. Key electrical characteristics include a collector-emitter saturation voltage of 300 mV maximum and a forward voltage of 1.2 V typical. It supports a maximum collector current of 30 mA and operates within a temperature range of -55°C to +100°C.
Feature Summary
- Integrates an AlGaAs LED with an NPN phototransistor for efficient optical coupling
- Provides robust electrical isolation with a rated voltage of 5000 Vrms
- Designed for surface-mount assembly in a compact four-pin configuration
Applications
- Industrial control systems requiring galvanic isolation
- Signal transmission across isolated power supply circuits
- Microcontroller interface circuits for noise immunity
Procurement Notes
Verify the specific suffix 'F3-L' against official Renesas documentation to confirm tape-and-reel packaging and lead-free compliance status. Confirm component availability as some variants may be designated as not recommended for new designs. Ensure the ordering part number matches the exact package style and termination requirements for your PCB layout.
Selection Notes
Select this component when a surface-mount solution is required for single-channel isolation applications. Consider the 30 mA collector current limit and 70 V collector-emitter voltage rating for circuit design compatibility. Verify that the operating temperature range meets the environmental conditions of the target application.
Part Context
This component belongs to the PS2561A series of transistor output optocouplers from Renesas Electronics. The series is known for combining high-speed performance with high isolation capabilities. The PS2561AL variant specifically utilizes an AlGaAs LED, which offers improved efficiency compared to standard GaAs LEDs found in other series members.
Replacement Considerations
Direct substitutes include PS2561AL-1-F3-A or PS2561AL-1-V-H-A if pinout and electrical parameters match. Verify package dimensions and isolation ratings before substitution.
