PS2706-1-A

Overview

The PS2706-1-A is a single-channel optoisolator manufactured by Renesas Electronics Corporation, featuring a Darlington transistor output. It provides an isolation voltage of 3750Vrms and operates within a temperature range of -55°C to 100°C. The device supports a maximum collector-emitter saturation voltage of 1V and a continuous output current of 200mA per channel. Key electrical parameters include a minimum current transfer ratio of 200% at 1mA input current, a typical forward voltage of 1.1V, and a maximum DC forward current of 50mA. The component utilizes a 4-SOP surface-mount package with rise and fall times of 200µs each.

Procurement Notes

Verify the specific suffix against official Renesas documentation to confirm exact packaging and tape/reel specifications. Ensure the procurement source provides valid RoHS compliance certificates matching the current manufacturing standard. Cross-reference the manufacturer part number with authorized distributor databases to confirm active status and availability before finalizing orders.

Selection Notes

Select this component when high current drive capability is required in a compact surface-mount form factor. The Darlington output offers superior gain compared to standard phototransistors, making it suitable for low-input-current applications. Verify that the 3750Vrms isolation rating meets the safety requirements of the target application circuit design.

Part Context

This component belongs to the NEPOC series of optocouplers from Renesas Electronics. It is designed for general-purpose isolation tasks where robust performance and reliability are critical. The PS2706 variant specifically targets applications needing higher output current handling than standard logic-level optocouplers provide.

Replacement Considerations

Consult official substitution lists for verified equivalents such as PS2706-1-F3-A or PS2706-4-E3-3400 depending on channel count and packaging requirements.
