Overview
The PS2381-1Y-F3-AX is a single-channel transistor output optocoupler manufactured by Renesas Electronics. It features an NPN phototransistor output and operates within an ambient temperature range of -40°C to +115°C. The device provides high isolation with a breakdown voltage (BV) of 5000 Vrms and a minimum isolation distance of 0.4 mm. Key electrical parameters include a maximum collector-emitter voltage of 80 V, a maximum collector current of 50 mA, and a forward voltage of 1.1 V at a forward current of 5 mA. Switching characteristics specify a rise time of 4 µs and a fall time of 5 µs. The unit is housed in a compact 4-pin LSOP surface-mount package.
Feature Summary
- High insulation voltage capability of 5000 Vrms for robust signal isolation
- Extended operating ambient temperature range up to 115°C
- Compact 4-pin LSOP surface-mount packaging design
Applications
- Industrial control systems requiring galvanic isolation
- Power supply feedback loops
- Signal transmission between isolated circuits
Procurement Notes
Verify component authenticity through authorized Renesas distributors or certified partners. Confirm the specific suffix F3 corresponds to the required tape and reel packaging configuration. Ensure compliance with RoHS directives as indicated in official documentation. Check for any recent lifecycle status updates regarding availability or obsolescence before finalizing procurement plans.
Selection Notes
Select this component when high isolation voltage and wide temperature operation are critical. The NPN phototransistor output suits digital switching applications. Verify that the 5000 Vrms rating meets system safety standards. Consider the LSOP package dimensions for PCB layout constraints. Ensure the 5 mA forward current requirement aligns with the driving circuit capabilities.
Part Context
This part belongs to the PS2381 series of transistor output optocouplers from Renesas Electronics. The series is designed for general-purpose isolation applications. The PS2381-1Y variant specifically denotes the single-channel configuration with NPN output. The F3 suffix typically indicates specific packaging and handling specifications defined by the manufacturer.
Replacement Considerations
Publicly confirmed parameter-equivalent substitutes include PS2381-1Y-AX and PS2381-1Y-V-F3-AX. Verify pinout compatibility and electrical specifications before substitution. Ensure the alternative part meets the same isolation voltage and temperature requirements.
