Overview
The PS2911-1-K-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 40V and a maximum collector current of 40mA. The device provides 2500Vrms isolation voltage and operates within a temperature range of -55°C to +100°C. Key electrical parameters include a forward current of 50mA, a forward voltage of 1.4V, and a collector-emitter saturation voltage of 300mV. The component is housed in a 4-pin SSOP package.
Feature Summary
- Provides high-voltage isolation between input and output circuits using optical transmission.
- Utilizes an NPN phototransistor for reliable digital signal switching applications.
- Designed for surface-mount installation to facilitate automated PCB assembly processes.
Applications
- Industrial control systems requiring galvanic isolation
- Power supply feedback loops
- Microcontroller interface circuits
Procurement Notes
Verify the specific suffix 'K' against the official Renesas datasheet to confirm package type and tape/reel specifications. Confirm RoHS compliance status and lifecycle stage, as components may be subject to obsolescence notices or manufacturing changes documented in Product Change Notices (PCNs). Ensure the supplier provides valid traceability documentation.
Selection Notes
Select this component when a single-channel transistor output is required with 2500Vrms isolation. Consider the 40V collector-emitter voltage limit and 40mA current capacity for load compatibility. Verify that the SSOP-4 package fits the available board space and thermal requirements compared to alternative packages like Mini-Flat.
Part Context
This part belongs to the PS2911 family of transistor output optocouplers from Renesas Electronics. The family offers various isolation voltages and packaging options. The PS2911-1-K-AX specifically denotes the standard isolation variant in an SSOP-4 configuration, distinct from higher isolation models like the PS2711 series.
Replacement Considerations
Check for direct substitutes such as PS2911-1-V-F3-AX if Mini-Flat packaging is acceptable. Verify pinout compatibility and electrical parameter equivalence before substitution. Consult manufacturer PCNs for potential form-fit-function changes in legacy replacements.
