PS2561AL1-1-A

Overview

The PS2561AL1-1-A is a single-channel transistor output optocoupler manufactured by Renesas Electronics. It features an NPN phototransistor output with a maximum collector-emitter voltage of 70V and a collector current rating of 30mA. The device provides 5000Vrms isolation voltage between input and output circuits. Typical switching characteristics include a rise time of 3µs and a fall time of 5µs. The forward voltage is typically 1.2V at a forward current of 10mA, with a maximum DC forward current of 80mA. The unit operates within a temperature range of -55°C to +100°C and is housed in a 4-pin DIP gull-wing surface mount package.

Feature Summary

• Provides high-voltage electrical isolation via a 5000Vrms dielectric barrier between the infrared LED input and the NPN phototransistor output.
• Features fast switching performance with typical rise and fall times of 3µs and 5µs respectively for signal transmission applications.
• Designed for wide operating temperature ranges extending from -55°C to +100°C to support industrial and harsh environment deployments.

Applications

• Industrial control systems requiring galvanic isolation for signal interfacing
• Solid-state relay (SSR) driver circuits
• Microcontroller interface isolation for digital communication lines

Procurement Notes

Verify component authenticity through authorized Renesas distributors or certified supply chain partners. Confirm that the specific suffix matches the required package and tape/reel specifications for automated assembly processes. Ensure compliance with RoHS3 and REACH regulations as documented in the official datasheet before integration into final products.

Selection Notes

Select this component when a single-channel isolation barrier is required with moderate speed requirements. Compare the 70V collector-emitter voltage limit against circuit load conditions. Verify that the 30mA output current capability meets the sink requirements of the downstream logic or relay coil. Consider thermal management within the specified -55°C to +100°C operational window.

Part Context

This part belongs to the PS2561 series of transistor output optocouplers. It shares functional similarities with other variants in the family but differs in specific electrical ratings and packaging configurations. The series is designed for general-purpose isolation tasks where cost-effective and reliable signal transfer is prioritized over high-speed data transmission capabilities found in faster optocoupler families.
