PS2561A-1-V-A

Overview

The PS2561A-1-V-A is a single-channel transistor output optocoupler manufactured by Renesas Electronics. It features an NPN phototransistor output and provides 5000 Vrms insulation voltage for effective signal isolation. The device operates with a maximum collector-emitter voltage of 70V and supports a maximum collector current of 30mA. Key electrical parameters include a forward voltage of 1.2V, a forward current rating of 10mA, and a collector-emitter saturation voltage of 300mV. Switching characteristics are defined by a rise time of 3µs and a fall time of 5µs. The component is housed in a standard DIP-4 package suitable for through-hole mounting.

Feature Summary

• Provides high-voltage isolation with 5000 Vrms insulation capability between input and output circuits.
• Features an NPN phototransistor output stage designed for reliable digital signal transmission.
• Offers fast switching performance with a typical rise time of 3µs and fall time of 5µs.

Applications

• Industrial control systems requiring galvanic isolation
• Power supply feedback loops for voltage regulation
• Communication interface isolation for data transfer

Procurement Notes

Verify the specific suffix 'A' against the official Renesas datasheet to confirm pinout configuration and packaging type. Check the lifecycle status as some variants may be marked NRND or obsolete. Ensure compliance with RoHS directives if required for your application. Confirm that the DIP-4 through-hole package matches your PCB design constraints before finalizing procurement orders.

Selection Notes

Select this component when a single-channel isolation solution with moderate speed is required. The 70V collector-emitter voltage rating suits low-to-medium voltage switching applications. Consider the 10mA forward current limit when designing the input circuitry. Verify that the 5000 Vrms isolation rating meets the safety standards applicable to your equipment category.
