Overview
The PS2381-1Y-M-AX is a single-channel transistor-output optoisolator manufactured by CEL. It features an NPN phototransistor output with a maximum collector-emitter voltage of 80V and a collector current of 50mA. The device provides high isolation capability with a breakdown voltage (BV) of 5,000 Vrms. Typical switching times include a rise time of 4µs and a fall time of 5µs. It operates within an ambient temperature range up to 115°C and utilizes a surface-mount LSOP-4 package.
Feature Summary
- Provides electrical isolation between control and load circuits using a transistor output configuration.
- Supports high-voltage isolation with a rated breakdown voltage of 5,000 Vrms.
- Designed for operation in elevated ambient temperatures up to 115°C.
Applications
- Signal isolation in industrial control systems
- Interface between microcontrollers and high-voltage loads
- Power supply feedback loops
Procurement Notes
Verify the specific suffix 'M' against the manufacturer's official documentation to confirm package type and tape/reel specifications. Ensure the component meets required isolation standards for the target application. Confirm availability status as distribution channels may vary. Cross-reference the datasheet revision date to ensure parameter accuracy.
Selection Notes
Select this component when a single-channel transistor output is required for galvanic isolation. Consider the 80V collector-emitter voltage rating and 50mA current capacity for load compatibility. Verify that the LSOP-4 package fits the PCB layout constraints. Check if the 4µs/5µs switching speeds meet the signal integrity requirements of the circuit design.
Part Context
This part belongs to the NEPOC series of optoisolators from CEL. It is functionally similar to other variants in the PS2381 family, differing primarily in packaging or reel specifications. The device serves as a standard solution for isolating low-voltage digital signals from higher-voltage analog or power domains.
Replacement Considerations
Direct substitutes include PS2381-1Y-F3-W-AX and PS2381-1Y-V-F3-AX. Verify pinout compatibility and package dimensions before substitution. Ensure replacement parts maintain the same 5,000 Vrms isolation rating and electrical characteristics.
