PS2561BL2-1-A

Overview

The PS2561BL2-1-A is a single-channel transistor output optocoupler manufactured by Renesas Electronics. It integrates a GaAs infrared LED and an NPN silicon phototransistor within a surface-mount DIP-4 gull-wing package designed for long creepage distance. The device provides high isolation with a rated insulation voltage of 5000 Vrms. Key electrical parameters include a maximum collector-emitter voltage of 80 V, a maximum collector current of 50 mA, and a power dissipation rating of 150 mW. It operates reliably across an ambient temperature range from -55°C to +110°C.

Feature Summary

Features a gull-wing lead bending design specifically engineered to provide extended creepage distance for enhanced safety isolation in surface mount applications.

Applications

High-voltage switching circuits requiring robust galvanic isolation
Industrial control systems operating at elevated temperatures
Power supply feedback loops for signal transmission

Procurement Notes

Verify the specific suffix against official Renesas documentation to confirm exact pin configuration and creepage specifications. Confirm availability status as distribution channels may list obsolete or not recommended for new designs variants. Ensure compliance with RoHS directives if required by the target application environment.

Selection Notes

Select this component when a surface mount solution with extended isolation creepage is required. The 110°C operating temperature capability distinguishes it from standard industrial grade alternatives. Verify that the 50 mA collector current limit meets the load requirements of the driven circuitry before integration.

Part Context

This part belongs to the PS2561B series of photocouplers. It shares the core optoelectronic structure with through-hole variants but utilizes a specialized SMD package. The BL2 designation indicates the specific lead form factor optimized for long creepage distance compared to standard gull-wing packages.
