Overview
The PS2381-1Y-F3-W-AX is a single-channel transistor output optocoupler manufactured by Renesas Electronics (formerly CEL). It features an NPN phototransistor output with a maximum collector-emitter voltage of 80 V and a collector current of 50 mA. The device provides high isolation with a breakdown voltage of 5000 Vrms and operates within a temperature range of -40°C to +115°C. Key electrical parameters include a forward current of 5 mA, forward voltage of 1.1 V, and saturation voltage of 300 mV. Switching characteristics consist of a rise time of 4 µs and a fall time of 5 µs. It is housed in a compact LSOP-4 surface-mount package.
Feature Summary
- High insulation voltage capability of 5000 Vrms for robust signal isolation
- Extended operating ambient temperature rating up to 115 °C
- Compact LSOP-4 surface-mount package design for space-constrained applications
Applications
- Industrial control systems requiring galvanic isolation
- Power supply feedback loops
- Signal transmission across isolated grounds
Procurement Notes
Verify component authenticity through authorized Renesas distributors or certified suppliers. Confirm the specific suffix 'F3' corresponds to the required tape and reel packaging configuration. Check for RoHS compliance documentation relevant to the manufacturing date code. Ensure storage conditions adhere to moisture sensitivity levels specified in the datasheet to maintain reliability during soldering processes.
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 50 mA collector current meets load requirements. Consider the LSOP-4 footprint compatibility with existing PCB layouts. Evaluate thermal management needs given the 115°C maximum operating temperature limit.
Part Context
This part belongs to the PS2381 series of transistor output optocouplers from Renesas Electronics. The series is designed for general-purpose isolation tasks. The manufacturer transitioned from California Eastern Laboratories (CEL) to Renesas Electronics. The product maintains consistent electrical specifications across similar package variants within the family line.
Replacement Considerations
Publicly confirmed parameter-equivalent substitutes include PS2381-1Y-AX and PS2381-1Y-V-F3-AX. Verify pinout compatibility and package dimensions before substitution. Ensure replacement parts meet the same 5000 Vrms isolation and 115°C temperature ratings.
