Overview
The PS2911-1-V-L-AX is a single-channel transistor output optocoupler manufactured by Renesas Electronics. It features an NPN phototransistor output and operates within a temperature range of -55°C to +100°C. The device provides 2500 Vrms isolation voltage and supports a maximum collector current of 40 mA with a collector-emitter voltage of 40 V. Key electrical parameters include a forward current of 50 mA, a forward voltage of 1.3 V, and a power dissipation of 180 mW. The unit utilizes a 4-pin SSOP surface-mount package.
Feature Summary
- Provides galvanic isolation between input and output circuits using infrared LED and NPN phototransistor technology.
- Features high current transfer ratio for efficient signal transmission across the isolation barrier.
- Designed for surface-mount installation in compact electronic assemblies.
Applications
- Industrial control systems requiring signal isolation
- Measurement equipment input stages
- Power supply feedback loops
Procurement Notes
Verify the specific suffix against official Renesas documentation to confirm pinout compatibility and package dimensions. Confirm RoHS compliance status and lifecycle stage prior to procurement. Ensure the supplier source is authorized to guarantee component authenticity and traceability.
Selection Notes
Select this component when a single-channel isolated interface with moderate speed requirements is needed. Consider the 4-pin SSOP footprint for PCB layout constraints. Evaluate thermal management needs based on the specified power dissipation limits under operating conditions.
Part Context
This part belongs to the PS2911 series of transistor output optocouplers from Renesas Electronics. The series is designed for general-purpose isolation applications. The specific model variant indicates the package type and regional manufacturing specifications defined by the manufacturer.
Replacement Considerations
Consult official cross-reference lists for verified substitutes. Ensure replacement parts match the 2500 Vrms isolation rating and 40 mA collector current capability. Verify package compatibility before integration.
