PS2381-1Y-V-L-AX

Overview

The PS2381-1Y-V-L-AX is a single-channel transistor output optoisolator manufactured by CEL. It features an NPN phototransistor output with a maximum collector-emitter voltage of 80 V and a collector current rating of 50 mA. The device provides high isolation capability with a breakdown voltage (BV) of 5,000 Vrms and a minimum isolation distance of 0.4 mm. It operates within an ambient temperature range up to 115 °C. Key electrical parameters include a forward voltage of 1.1 V at 5 mA forward current, a saturation voltage of 300 mV, and switching times of 4 µs rise and 5 µs fall.

Feature Summary

• High isolation voltage rating of 5,000 Vrms for robust electrical separation
• Compact 4-pin LSOP surface-mount package design
• Capable of operating in ambient temperatures up to 115 °C
• Fast switching performance with defined rise and fall times

Applications

• Industrial control systems requiring galvanic isolation
• Power management circuits for signal transmission
• Microcontroller interface isolation

Procurement Notes

Verify the specific suffix 'V-L-AX' against official datasheets to ensure compatibility with required packaging and tape-and-reel specifications. Confirm that the manufacturer designation aligns with current corporate structures, as Renesas Electronics has acquired former CEL assets. Check for any lifecycle status updates or obsolescence notices directly from the supplier before finalizing procurement plans.

Selection Notes

Select this component when a single channel of high-voltage isolation is required in a compact surface-mount footprint. Ensure the application voltage does not exceed the 80 V collector-emitter limit and that the load current remains within the 50 mA specification. Verify that the 5,000 Vrms isolation rating meets the safety standards of the target system.

Part Context

This part belongs to the PS2381 family of transistor output optoisolators. These devices are designed to provide electrical isolation between input and output circuits while transmitting digital signals. The family typically offers various packaging options and insulation ratings suitable for general-purpose isolation applications in industrial and consumer electronics.

Replacement Considerations

The PS2381-1Y-F3-W-AX is a related variant within the same product family. Verify pinout compatibility and specific electrical parameter differences before substitution.
