PS2561L1-1-L-A

Overview

The PS2561L1-1-L-A is a single-channel transistor output optocoupler manufactured by CEL. It features a GaAs LED and an NPN silicon phototransistor within a 4-pin DIP package designed for through-hole mounting. The device provides high isolation voltage of 5000 Vrms, ensuring robust signal transmission across isolated circuits. Key electrical parameters include a minimum current transfer ratio of 100% and a maximum collector-emitter voltage of 80 V. It operates within a temperature range of -55°C to +100°C, supporting reliable performance in various industrial applications requiring galvanic isolation.

Feature Summary

High isolation voltage capability for safe circuit separation
Single channel configuration with NPN phototransistor output
Through-hole mountable 4-pin DIP package design

Applications

Industrial control systems requiring signal isolation
Power supply feedback loops
Microcontroller input interfacing

Procurement Notes

Verify component authenticity and datasheet alignment before integration. Confirm package dimensions and pinout compatibility with existing PCB footprints. Check for end-of-life status or discontinuation notices from the manufacturer. Ensure replacement parts meet identical electrical specifications if sourcing alternatives. Validate safety certifications required for the specific application environment.

Selection Notes

Choose this component when high isolation voltage and through-hole mounting are required. Consider the current transfer ratio limits for driving subsequent stages. Evaluate thermal management needs given the operating temperature range. Compare against surface-mount variants if space constraints exist. Verify that the NPN output type matches the logic requirements of the receiving circuit.

Part Context

This part belongs to the NEPOC series of photocouplers from CEL. It shares architectural similarities with other PS2561 family members but differs in package style and lead configuration. The L1 designation typically indicates a specific lead bending type for improved creepage distance compared to standard DIP versions. It serves as a discrete isolation solution within broader power and signal conditioning designs.
