Overview
The PS2705-1-L-A is a single-channel optocoupler featuring an NPN phototransistor output and GaAs LED input. It provides 3750 Vrms isolation voltage and supports AC/DC input signals. Key electrical parameters include a maximum collector-emitter voltage of 40V, peak collector current of 80mA, and forward current of 50mA. Typical switching times are 3µs rise and 5µs fall. The device operates within a temperature range of -55°C to +100°C.
Feature Summary
- High isolation voltage capability for safety-critical applications
- AC input response functionality for direct signal coupling
- SOP package design with ambient light shielding effect
- High-speed switching performance suitable for dense mounting
Applications
- Industrial control systems requiring high isolation
- Solid-state relay driver circuits

- Power supply feedback loops
Procurement Notes
Verify component authenticity through authorized Renesas distributors or certified partners. Confirm RoHS compliance status and specific suffix variations against official datasheets prior to ordering. Check current availability as stock levels may fluctuate due to limited supply conditions. Ensure storage and handling procedures meet moisture sensitivity level requirements.
Selection Notes
Select this component when high isolation voltage and AC input compatibility are required in a compact SOP package. Consider the 40V collector-emitter voltage limit and 80mA peak current capacity for load matching. Evaluate thermal dissipation requirements given the 150mW power rating. Compare switching speeds against system timing constraints before finalizing the design choice.
Part Context
This part belongs to the PS2705 series of high-isolation voltage photocouplers manufactured by Renesas Electronics. The series utilizes a Small Outline Package (SOP) configuration designed for high-density surface-mount applications. The product line emphasizes cost-performance balance while maintaining robust electrical isolation characteristics for industrial environments.
Replacement Considerations
PS2705-1-F3-A and PS2705-1-F4-L-A are documented variants within the same family. Verify pinout compatibility and electrical parameter alignment before substitution. Suffix differences may indicate packaging or manufacturing changes rather than functional alterations.
