PS2913-1-A

Overview

The PS2913-1-A is a single-channel transistor output optocoupler featuring an NPN silicon phototransistor and a GaAs infrared LED. It provides 2500 Vrms isolation voltage and operates within a temperature range of -55°C to 100°C. The device utilizes a 4-pin ultra-small flat-lead surface mount package measuring 4.60 x 2.50 mm with a height of 2.10 mm. Key electrical parameters include a collector-emitter breakdown voltage of 120 V, a maximum forward current of 50 mA, and a typical current transfer ratio of 100%. The component is lead-free and RoHS compliant.

Feature Summary

• Integrates a GaAs light emitting diode and an NPN silicon phototransistor for high-density mounting applications.
• Utilizes an ultra-small flat-lead package that reduces mounting area by approximately 30% compared to standard packages.
• Provides high collector-to-emitter voltage capability suitable for various isolation requirements.

Applications

• High-density circuit board mounting
• Signal isolation in electronic circuits
• General purpose optically coupled isolators

Procurement Notes

Verify the specific suffix (e.g., F3, AX) against the required datasheet revision, as packaging and tape/reel specifications may vary. Confirm current availability status, as this part number may be obsolete or restricted depending on the manufacturer's lifecycle stage. Ensure the selected variant matches the required isolation voltage and pin configuration for the target design.

Selection Notes

Select this component when space constraints require a compact footprint without sacrificing isolation performance. The 2500 Vrms rating supports general industrial isolation needs. Consider the 120 V collector-emitter breakdown voltage for load switching applications. Verify thermal management requirements given the small package size and operating temperature range up to 100°C.

Part Context

This component belongs to the NEC/CEL PS2913 series of single-channel photocouplers. The series is characterized by its ultra-small form factor designed to minimize PCB real estate. It serves as a direct replacement for larger traditional optocouplers in applications where space is limited but electrical isolation remains critical for safety and noise immunity.

Replacement Considerations

Check for direct substitutes such as the PS2913-1-F3-A or PS2913-1-M-A if the base PS2913-1-A is unavailable. Verify pinout compatibility and package dimensions before substitution. Note that some variants may have different packaging quantities or minor parameter tolerances.
