PS2381-1Y-V-F3-AX

Overview

The PS2381-1Y-V-F3-AX is a single-channel transistor output optocoupler manufactured by Renesas Electronics. It features an NPN phototransistor output and operates with a forward current of 5 mA and a forward voltage of 1.1 V. The device provides high isolation with a breakdown voltage of 5000 Vrms and a minimum creepage distance of 8 mm. Electrical characteristics include a maximum collector-emitter voltage of 80 V, a maximum collector current of 50 mA, and a saturation voltage of 300 mV. Switching performance is defined by a rise time of 4 µs and a fall time of 5 µs. The component supports a reverse voltage of 6 V and dissipates up to 250 mW. It functions within an ambient temperature range of -40°C to +115°C.

Feature Summary

• High isolation voltage rating of 5000 Vrms for robust electrical separation
• Extended operating ambient temperature capability up to 115°C
• Minimum 8 mm creepage distance for enhanced safety compliance
• Single channel configuration with NPN phototransistor output

Applications

• Industrial control systems requiring galvanic isolation
• Power supply feedback loops
• Signal transmission across isolated ground domains

Procurement Notes

Verify the specific suffix 'V' indicates the required 8mm creepage distance, as standard versions may differ. Confirm RoHS compliance status through official documentation before integration. Check current availability as distribution channels may report limited stock or discontinuation status. Ensure the LSOP-4 package dimensions match the target PCB footprint constraints during the design phase.

Selection Notes

Select this component when high isolation voltage and extended temperature operation are critical requirements. The 8mm creepage distance makes it suitable for applications demanding strict safety clearance standards. Compare switching speeds against system timing requirements, noting the 4µs rise time. Consider the NPN output type for compatibility with existing logic interfaces without additional pull-up components if sourcing similar variants.

Part Context

This part belongs to the PS2381 series of optically coupled isolators from Renesas Electronics. The series utilizes a GaAs light emitting diode paired with an NPN silicon phototransistor. The PS2381-1 variant specifically denotes the single-channel configuration housed in a 4-pin LSOP package. This family is designed for general-purpose isolation tasks in electronic circuits.

Replacement Considerations

Publicly confirmed parameter-equivalent substitutes include PS2381-1Y-AX and PS2381-1Y-V-AX. Verify that alternative parts maintain the 5000 Vrms isolation rating and 8mm creepage distance if the 'V' suffix requirement is mandatory. Cross-reference pinouts and thermal dissipation characteristics to ensure functional compatibility.
