PS2561-1-L-A

Overview

The PS2561-1-L-A is a single-channel transistor output optocoupler manufactured by Renesas Electronics. It integrates a GaAs infrared LED and an NPN silicon phototransistor in a surface-mount DIP-4 gull wing package. Key electrical parameters include a maximum collector-emitter voltage of 80 V, a maximum collector current of 50 mA, and a forward voltage of 1.17 V at 10 mA. The device provides 5000 Vrms isolation voltage with typical rise and fall times of 3 µs and 5 µs respectively. It operates within a temperature range of -55°C to +100°C.

Feature Summary

Integrates a GaAs light emitting diode and an NPN silicon phototransistor for signal transmission
Provides high insulation voltage capability for circuit isolation
Designed for surface mount installation using a four-pin gull wing package

Applications

General purpose digital signal isolation
Microprocessor input/output interface circuits
Solid state relay driver applications

Procurement Notes

Verify component status as the part may be classified as obsolete or not recommended for new designs. Confirm availability through authorized distributors as stock levels vary. Ensure compliance with RoHS3 specifications and check for any recent product change notices regarding manufacturing location or material composition before finalizing procurement plans.

Selection Notes

Select this component when a surface-mount solution is required for single-channel isolation with moderate speed requirements. Compare against the through-hole PS2561-1-A variant if PCB space constraints are not critical. Verify that the 50 mA collector current rating meets the load requirements of the destination circuit. Consider thermal dissipation limits within the small SMD package during high-frequency operation.

Part Context

This device belongs to the PS2561 series of high isolation voltage photocouplers from Renesas. The series includes various packages such as standard DIP and flat pack options. The PS2561-1-L-A specifically denotes the surface-mount version with the L suffix indicating the lead-free gull wing configuration. It shares core electrical characteristics with other members of the family while differing primarily in mechanical footprint.
