Overview
The PS2381-1Y-W-AX is a single-channel optoisolator manufactured by CEL, featuring a DC input and NPN transistor output. It provides high isolation voltage of 5000Vrms with an isolation distance of at least 0.4 mm. The device operates within an ambient temperature range up to 115 °C. Key electrical parameters include a typical forward voltage (Vf) of 1.1V, a maximum output voltage of 80V, and a channel output current of 50mA. Current transfer ratio ranges from 130% to 260% at 5mA input.
Feature Summary
- High isolation voltage capability of 5000Vrms for robust signal separation
- Compact physical design with minimum 0.4 mm isolation distance
- Wide operating ambient temperature range extending to 115 °C
Applications
- Industrial control systems requiring galvanic isolation
- Signal transmission between microcontrollers and power circuits
- Noise immunity enhancement in sensitive measurement equipment
Procurement Notes
Verify the specific suffix 'W' against official Renesas or CEL documentation to confirm package type and tape/reel specifications. Ensure the component matches the required isolation voltage rating of 5000Vrms for your application safety standards. Cross-reference the manufacturer part number to avoid confusion with similar variants like the F3 version.
Selection Notes
Select this component when a single-channel transistor output optocoupler with high isolation voltage is required. Consider the 50mA output current limit and 80V maximum output voltage for load compatibility. Verify that the 115 °C operating temperature meets your environmental constraints. Compare current transfer ratio specifications if precise gain is critical for the circuit design.
Part Context
This part belongs to the NEPOC series of optoisolators from CEL, now part of Renesas Electronics. It is designed for applications needing reliable electrical isolation between low-voltage control circuits and higher-voltage loads. The series emphasizes compact size and high reliability in industrial environments.
Replacement Considerations
Check for direct substitutes such as the PS2381-1Y-F3-W-AX, which shares similar isolation characteristics but may differ in packaging or reel configuration. Verify pinout compatibility and electrical ratings before substitution to ensure circuit integrity.
