Overview
The PS2561AL-1-H-A is a single-channel transistor output optocoupler manufactured by CEL. It integrates a Gallium Arsenide (GaAs) infrared emitting diode with an NPN silicon phototransistor in a surface-mount plastic package. The device provides high isolation voltage of 5000 Vrms between input and output circuits. Key electrical parameters include a maximum collector-emitter saturation voltage of 300 mV, a rise time of 3 µs, and a fall time of 5 µs. It supports a maximum forward current of 30 mA and a collector current of 30 mA, with a maximum collector-emitter voltage rating of 70 V.
Feature Summary
- High isolation voltage capability for safe signal transmission across isolated domains
- Fast switching performance with defined rise and fall times for digital applications
- Low collector-emitter saturation voltage to minimize power loss in the output stage
Applications
- Industrial control systems requiring galvanic isolation
- Signal transmission between microcontrollers and peripheral devices
- Power supply feedback loops for voltage regulation
Procurement Notes
Verify the specific suffix 'H-A' against official manufacturer documentation to confirm tape-and-reel packaging configuration and lead-free compliance status. Ensure the component matches the exact pinout and thermal characteristics required for the target PCB layout. Cross-reference safety certifications such as UL or CSA if used in regulated equipment.
Selection Notes
Select this component when high isolation voltage and fast switching speeds are critical for system reliability. The low saturation voltage makes it suitable for low-voltage logic interfaces. Verify that the operating temperature range and forward current requirements align with the application's environmental conditions and drive capabilities.
Part Context
This part belongs to the PS2561A series of photocouplers, which utilize a GaAs LED and NPN phototransistor architecture. The series is designed for cost-effective isolation solutions in compact surface-mount packages. Variants within the series differ primarily in package type and current transfer ratio specifications.
Replacement Considerations
Direct replacements may include PS2561AL-1-E3-A or PS2561AL2-1-E3-A from compatible manufacturers, provided pinouts and electrical ratings match. Verify that substitute components maintain equivalent isolation voltage and switching speed characteristics.
