Overview
The PS2915-1-F3-A is a transistor output optocoupler manufactured by CEL. It features a high-speed digital output configuration with an integrated power supply and signal modulation circuit. The device utilizes GaAs light emitting diodes and an NPN silicon phototransistor within a single package. It is housed in an ultra-small flat-lead surface mount package measuring 4.6 mm in width, 2.5 mm in length, and 2.1 mm in height. The component supports AC and DC input types.
Feature Summary
- High-speed digital output isolator design
- Integrated power supply and signal modulation circuit
- Ultra-small flat-lead surface mount package
Applications
- Digital signal isolation
- Microprocessor interface circuits
- Industrial control systems
Procurement Notes
Verify part status carefully as the PS2915-1-F3-A is listed as obsolete and no longer manufactured by CEL. Confirm availability of parametric equivalents or alternative sources before procurement planning. Ensure compatibility with existing PCB footprints and verify RoHS compliance status for current stock units.
Selection Notes
Select this component only if legacy compatibility is required or if specific integration of power supply and modulation circuits is necessary. Consider that the device is obsolete; evaluate modern replacements with similar CTR specifications and package dimensions. Verify input type support for both AC and DC applications during design validation.
Part Context
This component belongs to the PS2915 series of optically coupled isolators. The series typically combines GaAs LEDs with NPN silicon phototransistors. The -F3-A suffix indicates specific packaging and tape-and-reel configuration details. The manufacturer CEL produces this variant as a specialized high-speed digital isolator solution.
Replacement Considerations
Parametric equivalents are available as substitutes. Verify electrical characteristics such as current transfer ratio and propagation delay when selecting alternatives. Ensure the replacement maintains the 4-SMD flat lead package form factor for direct board compatibility.
