Overview
The PS2911-1-M-AX is a single-channel transistor output optocoupler manufactured by Renesas Electronics. It features an NPN phototransistor output with a maximum collector-emitter voltage of 40 V and a maximum collector current of 40 mA. The device provides an isolation voltage of 2500 Vrms and operates within a temperature range of -55°C to +100°C. Key electrical parameters include a forward current of 50 mA, a forward voltage of 1.3 V maximum, and a power dissipation of 160 mW. The current transfer ratio ranges from 100% to 200%, with a collector-emitter saturation voltage of 300 mV maximum.
Feature Summary
- Provides galvanic isolation between input and output circuits using a single channel configuration.
- Utilizes an NPN phototransistor output for DC signal transmission applications.
- Designed for surface mount installation in compact SSOP-4 or Mini-Flat packages.
Applications
- Industrial control systems requiring signal isolation
- Measurement equipment input stages
- Power supply feedback loops
Procurement Notes
Verify the manufacturer designation carefully, as this part number has been associated with different suppliers including CEL and California Eastern Labs in public databases. Confirm the specific package variant (SSOP-4 vs Mini-Flat) and ensure the component status aligns with project requirements, as some listings indicate unconfirmed status or discontinuation. Cross-reference the datasheet revision to confirm compliance with RoHS standards and specific electrical tolerances before procurement.
Selection Notes
Select this component when a single-channel transistor output optocoupler with 2500 Vrms isolation is required. Ensure the application supports the specified 40 V collector-emitter voltage and 40 mA collector current limits. Verify that the operating temperature range of -55°C to +100°C meets environmental constraints. Consider the package type availability, as discrepancies exist between SSOP-4 and Mini-Flat configurations in public records.
Part Context
This component belongs to the PS2911 series of transistor output optocouplers. The series is designed for general-purpose isolation applications. The 'M' suffix typically denotes a specific package or speed grade variation within the family, though public documentation varies on its exact definition across different manufacturers. The device serves as a bridge for transferring digital signals while maintaining electrical safety separation.
Replacement Considerations
Public data lists PS2911-1-V-F3-AX and PS2911-1-AX as related variants within the same product family. Verify pinout compatibility and electrical specifications against the original design requirements before substitution, as package types and specific CTR ranges may differ between these part numbers.
