Overview
The PS2381-1Y-F3-AX is a single-channel optoisolator manufactured by CEL. It integrates a Gallium Arsenide (GaAs) infrared light-emitting diode with an NPN silicon phototransistor to provide electrical isolation between input and output circuits. The device operates in a surface-mount 4-LSOP package with a lead pitch of 2.54mm. Key electrical specifications include a high isolation voltage rating of 5000Vrms and a minimum isolation distance of 0.4mm. The component supports an operating ambient temperature up to 115°C, ensuring reliability in demanding thermal environments.
Feature Summary
- Combines a GaAs LED with an NPN silicon phototransistor for efficient optical coupling
- Provides robust electrical isolation with a 5000Vrms rating
- Designed for surface-mount assembly in compact 4-LSOP packages
Applications
- Isolation between control logic and load circuits
- Signal transmission across isolated boundaries
- Protection of low-voltage control systems from high-voltage loads
Procurement Notes
Verify the specific suffix 'F3' against the manufacturer's current datasheet to confirm pinout compatibility and package dimensions. Confirm whether the part status is active or discontinued, as availability may vary. Ensure the required isolation voltage and temperature ratings meet the design specifications before procurement.
Selection Notes
Select this component when high isolation voltage is required in a small surface-mount footprint. The NPN phototransistor output is suitable for digital signal switching applications. Consider the 115°C operating temperature limit for high-thermal environments. Verify that the 4-pin LSOP package fits the PCB layout constraints.
Part Context
This device belongs to the PS2381 family of transistor-output optoisolators. These components are designed for general-purpose isolation tasks where reliable signal transfer is critical. The family typically offers various package options and isolation ratings to suit different industrial and commercial applications.
Replacement Considerations
Check for direct substitutes within the PS2381 series, such as variants with different suffixes like 'L' or 'W', which may share similar electrical characteristics but differ in packaging or compliance features. Verify pinout compatibility before substitution.
