Overview
The PS2913-1-K-A is a single-channel optically coupled isolator manufactured by CEL. It integrates a Gallium Arsenide (GaAs) infrared emitting diode with an NPN silicon phototransistor within a compact package designed for high-density mounting. The device provides electrical isolation between input and output circuits, characterized by a rated isolation voltage of 2500Vrms. Key electrical specifications include a minimum current transfer ratio of 100% at a forward current of 1mA and a maximum collector-emitter saturation voltage of 300mV. The component supports a maximum collector current of 30mA and operates within a standard temperature range.
Feature Summary
- Integrates GaAs LED and NPN phototransistor for signal isolation
- Designed for high-density surface-mount applications
- Provides robust electrical isolation between input and output circuits
Applications
- Industrial control systems requiring signal isolation
- Measurement equipment needing circuit separation
- Power supply feedback loops
Procurement Notes
Verify the specific suffix 'K-A' against official manufacturer documentation to confirm pinout and packaging details. Note that this specific part number may be obsolete; confirm availability status and lead times directly with authorized distributors or CEL before procurement planning.
Selection Notes
Select this component when a single-channel transistor-output optocoupler with 2500Vrms isolation is required. Ensure the application demands a current transfer ratio compatible with the specified 100-200% range at 1mA input. Verify that the 30mA collector current limit meets the load requirements of the target circuit design.
Part Context
This device belongs to the PS2913 family of optocouplers from CEL (California Eastern Laboratories). These components are engineered for general-purpose isolation tasks where space constraints necessitate compact packaging. The family typically offers variants with different pin configurations or tape-and-reel options, such as the PS2913-1-F3 series.
Replacement Considerations
Official sources indicate the PS2913-1-K-A is obsolete. The parametric equivalent PS2913-1 is listed as an available substitute. Verify pin compatibility and electrical parameters before substituting.
