PS2561BL1-1-D-A

Overview

The PS2561BL1-1-D-A is a single-channel transistor output optocoupler manufactured by CEL. It integrates a GaAs infrared emitting diode and an NPN silicon phototransistor in a lead bending type package designed for surface mount applications with extended creepage distance. The device supports an operating ambient temperature range from -55 °C to 110 °C. Key electrical specifications include a minimum collector-emitter breakdown voltage of 80 V, a maximum forward current of 40 mA, and a typical current transfer ratio of 200%. It provides high isolation capability with a rated insulation voltage of 5000 Vrms.

Feature Summary

High isolation voltage rating of 5000 Vr.m.s. for reliable signal transmission across isolated circuits
Extended creepage distance design via wide lead bending configuration for enhanced safety compliance
Wide operating temperature range supporting functionality from -55 °C to 110 °C
High current transfer ratio ensuring efficient coupling between input LED and output phototransistor

Applications

Industrial control systems requiring galvanic isolation
Power supply feedback loops for voltage regulation
Signal transmission in noisy electromagnetic environments
Microcontroller interface circuits for level shifting and protection

Procurement Notes

Verify the manufacturer designation on the component marking to confirm CEL origin, as this family is also produced by Renesas and NEC. Ensure the ordering suffix matches the specific lead form and packaging requirements. Confirm RoHS compliance status if restricted substances are a constraint for the assembly process. Cross-reference the datasheet revision date to ensure parameter consistency with the production batch.

Selection Notes

Select this component when a surface mount solution with increased creepage distance is required compared to standard DIP packages. The 80 V collector-emitter voltage rating suits low-voltage switching applications. Verify that the 40 mA maximum forward current meets the drive capabilities of the source circuit. Consider the 110 °C maximum operating temperature for high-thermal environments where standard 70 °C or 85 °C devices would fail.

Part Context

This part belongs to the PS2561B/L series of photocouplers, which utilize a GaAs LED and NPN phototransistor architecture. The BL1 variant specifically denotes a lead bending type for surface mount with long creepage distance. While originally developed by NEC, the technology is licensed and manufactured by multiple vendors including CEL and Renesas, maintaining functional equivalence within the series.
