Overview
The PS2911-1-M-A is a single-channel transistor output optocoupler manufactured by CEL. It integrates a GaAs infrared emitting diode and an NPN silicon phototransistor in a compact package. Key electrical parameters include a minimum isolation voltage of 2500 Vrms, a maximum collector-emitter voltage of 40 V, and a maximum collector current of 40 mA. The device operates within a temperature range of -55°C to +100°C with a power dissipation of 160 mW.
Feature Summary
- Provides high-voltage electrical isolation between input and output circuits using optical coupling technology.
- Features a compact physical footprint designed for surface-mount assembly on printed circuit boards.
- Utilizes an NPN phototransistor output stage suitable for digital signal transmission and switching applications.
Applications
- Industrial control systems requiring signal isolation
- Power supply feedback loops
- Microcontroller interface circuits
Procurement Notes
Verify the specific suffix 'M' against manufacturer documentation to confirm package type and tape-and-reel specifications. Confirm RoHS compliance status and lead times directly with authorized distributors or the manufacturer, as availability may vary by region and production batch.
Selection Notes
Select this component when a low-cost, single-channel isolation solution is required for moderate-speed digital signals. Ensure the 40 V collector-emitter voltage rating exceeds the load voltage requirements. Verify that the 40 mA collector current capability matches the downstream circuit demands.
Part Context
This part belongs to the PS2911 series of optocouplers from CEL. The series typically offers various package options and performance grades. The PS2911-1-M-A specifically denotes a single-channel configuration with defined thermal and electrical characteristics distinct from other variants in the family.
Replacement Considerations
Cross-reference with PS2911-1-L-A or PS2911-1-V-F3-AX for similar functionality. Verify pinout compatibility and electrical parameter margins before substitution. Consult official datasheets to ensure equivalent isolation ratings and package dimensions.
