PS2561L-1-V-E3-H-A

Overview

The PS2561L-1-V-E3-H-A is a single-channel transistor output optocoupler manufactured by CEL. It integrates a GaAs infrared emitting diode and an NPN silicon phototransistor within a surface-mount plastic package. The device provides high isolation voltage of 5000 Vrms between input and output circuits. Key electrical parameters include a maximum collector-emitter voltage of 80 V, a maximum forward current of 10 mA, and a typical current transfer ratio of 200%. It operates within a temperature range of -55 °C to +100 °C.

Feature Summary

• High isolation voltage capability for safe signal transmission across potential barriers
• Surface mount construction with lead bending design for automated assembly
• Single channel configuration integrating LED and phototransistor

Applications

• Industrial control systems requiring galvanic isolation
• Signal transmission in noisy electrical environments
• Power supply feedback loops for circuit protection

Procurement Notes

Verify the manufacturer designation as CEL (California Eastern Laboratories) rather than Renesas or NEC, as part numbers in this series are shared across multiple producers. Confirm the specific suffix 'V-E3-H-A' matches the required surface mount package type and lead-free compliance status. Check RoHS directives and safety certifications such as UL or CSA if required for your specific application standards.

Selection Notes

Select this component when a surface mount transistor output optocoupler with 5000 Vrms isolation is required. Ensure the 80 V collector-emitter voltage rating meets the load requirements. Verify that the 10 mA forward current limit is compatible with the driving circuit. Consider the operating temperature range of -55 °C to +100 °C for environmental suitability.

Part Context

This part belongs to the PS2561L series of photocouplers, which are designed for cost-effective isolation solutions. The series includes various package types such as DIP and surface mount variants. The L-series typically denotes lead-bending types suitable for SMT processes. This specific variant is produced by CEL, distinguishing it from similar parts made by NEC or Renesas.

Replacement Considerations

Direct substitutes may include PS2561L-1-E3 or PS2561L-1-F3 from other manufacturers like Renesas or NEC, provided the pinout and electrical characteristics match. Verify that the replacement maintains the same 5000 Vrms isolation rating and surface mount package dimensions.
