PS2761B-1Y-A

Overview

The PS2761B-1Y-A is a single-channel transistor output optocoupler manufactured by Renesas Electronics. It integrates a GaAs infrared emitting diode and an NPN silicon phototransistor within a plastic SOP-4 package. Key electrical parameters include a maximum collector-emitter voltage of 70 V, a maximum collector current of 50 mA, and a forward voltage of 1.1 V at 5 mA forward current. The device provides high isolation with a rated insulation voltage of 3750 Vrms and operates across a wide ambient temperature range from -55°C to +110°C.

Feature Summary

• High-speed switching capability with typical rise time of 4 μs and fall time of 5 μs
• Shielded package design that effectively cuts off ambient light interference
• Wide operating ambient temperature range extending up to 110°C for demanding environments

Applications

• Industrial control systems requiring signal isolation
• Power supply feedback loops
• Microcontroller input/output isolation

Procurement Notes

Verify the specific suffix 'Y' against official datasheets to confirm tape-and-reel packaging specifications. Confirm RoHS compliance status through the manufacturer's documentation. Ensure the sourcing channel provides valid traceability for this component. Check for any obsolescence notices or lifecycle changes directly from Renesas Electronics before finalizing procurement plans.

Selection Notes

Select this component when a compact SOP-4 footprint is required alongside high isolation voltage ratings. The 110°C operating temperature makes it suitable for industrial applications where standard commercial grade parts may fail. Compare the 50 mA collector current limit against load requirements to ensure adequate drive capability without exceeding saturation voltage limits.

Part Context

This part belongs to the PS2761B series of NEC/Renesas photocouplers. It shares functional similarities with other members like the PS2761B-1-F3-L-A but differs in packaging format and specific ordering suffixes. The series is designed for general-purpose isolation tasks where small size and high reliability are prioritized over ultra-high speed performance.

Replacement Considerations

PS2761B-1-F3-L-A offers similar electrical characteristics but utilizes a different taping product configuration.
