PS2381-1Y-V-W-AX

Overview

The PS2381-1Y-V-W-AX is a single-channel transistor output optocoupler manufactured by CEL. 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 capability with a breakdown voltage of 5000 Vrms and a minimum isolation distance of 0.4 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 an operating ambient temperature up to 115 °C and is housed in a 4-pin LSOP surface-mount package.

Feature Summary

• High isolation voltage rating of 5000 Vrms for robust signal transmission across isolated domains
• Compact 4-pin LSOP surface-mount package design suitable for space-constrained PCB layouts
• Fast switching response with specified rise and fall times for efficient digital signal processing
• Wide operating temperature range supporting industrial applications up to 115 °C

Applications

• Industrial control systems requiring galvanic isolation between microcontrollers and power stages
• Signal transmission in noisy electrical environments where ground loop prevention is critical
• Interface circuits connecting low-voltage logic devices to higher-voltage loads

Procurement Notes

Verify the specific suffix 'V' against official Renesas or CEL documentation to confirm exact binning or tape-and-reel specifications. Confirm RoHS compliance status directly from the manufacturer's latest datasheet revision. Check part availability as distribution channels may list discontinued or limited-stock items. Ensure the ordering part number matches the required package variant and isolation rating before finalizing procurement orders.

Selection Notes

Select this component when a single-channel transistor output optocoupler with high isolation voltage is required. The 5000 Vrms rating suits applications demanding significant potential difference separation. Consider the 4-pin LSOP package for surface-mount assembly constraints. Verify that the NPN output configuration aligns with the downstream circuit requirements. Ensure the operating temperature range meets the environmental conditions of the target application.
