PS2561L1-1-V-D-A

Overview

The PS2561L1-1-V-D-A is a single-channel transistor output optocoupler manufactured by Renesas Electronics. It features an NPN phototransistor output and provides 5000 Vrms isolation voltage. The device operates with a maximum forward current of 10 mA and a typical forward voltage of 1.17 V. It supports a collector-emitter voltage of 80 V and a collector current of 50 mA, with a saturation voltage of 300 mV. The unit has a power dissipation rating of 150 mW and a CTR of 200%. Switching times are specified at 3 µs rise and 5 µs fall. It functions within a temperature range of -55°C to +100°C.

Feature Summary

• Provides high-voltage electrical isolation between input and output circuits
• Utilizes an NPN phototransistor for digital signal transmission
• Designed for surface-mount installation in compact electronic assemblies

Applications

• Industrial control systems requiring circuit isolation
• Signal transmission across isolated boundaries in measurement equipment
• Power supply feedback loops for voltage regulation

Procurement Notes

Verify component authenticity through authorized channels due to limited availability status. Confirm RoHS compliance details prior to integration. Check for specific manufacturing date codes if long-term reliability is critical. Ensure the supplier provides valid traceability documentation. Validate that the package type matches the intended PCB footprint requirements.

Selection Notes

Select this component when a single-channel isolation barrier is required with moderate speed switching characteristics. The 5000 Vrms rating suits applications needing robust noise immunity. Consider the 10 mA forward current limit when designing drive circuits. Verify thermal management capabilities given the 150 mW power dissipation constraint in enclosed environments.
