Overview
The PS2561L-1-H-A is a single-channel transistor output optocoupler manufactured by CEL. It integrates a GaAs infrared emitting diode and an NPN silicon phototransistor within a four-pin gull-wing surface mount package. The device provides high isolation voltage of 5000 Vrms between input and output circuits. Key electrical parameters include a maximum collector-emitter voltage of 80 V, a forward current of 10 mA, and a typical current transfer ratio ranging from 80% to 400% at 5 mA. Operating temperatures span from -55°C to +100°C.
Feature Summary
- High insulation voltage capability for safe signal transmission across isolated domains
- Surface mount gull-wing package design for automated PCB assembly
- Single channel configuration with NPN phototransistor output
Applications
- Industrial control systems requiring galvanic isolation
- Signal transmission in microprocessor interface circuits
- Power supply feedback loop isolation
Procurement Notes
Verify the specific suffix H-A against official datasheets to confirm lead form and packaging type. Confirm RoHS compliance status as manufacturing processes evolve. Check for obsolescence notices or lifecycle changes directly from the manufacturer before finalizing procurement plans.
Selection Notes
Select this component when high isolation voltage is required in a compact surface mount footprint. Ensure the NPN output type matches the receiving circuit requirements. Verify that the operating temperature range meets the environmental conditions of the target application.
Part Context
This part belongs to the PS2561 series of high isolation voltage photocouplers. The series includes various package options such as DIP and different surface mount lead configurations. The L-series typically denotes surface mount variants with gull-wing leads suitable for modern PCB technologies.
Replacement Considerations
Direct replacements may include PS2561L-1-V-H-A or PS2561L-1-E3-H-A depending on specific lead-free or taping requirements. Cross-reference pinouts and electrical characteristics carefully before substitution.
