Overview
The PS2501L-1-L-A is a single-channel transistor output optocoupler manufactured by CEL. It integrates an AlGaAs light-emitting diode with an NPN silicon phototransistor to provide electrical isolation. The device features a high insulation voltage of 5000 VRMS and operates within a temperature range of -55°C to +100°C. It utilizes a surface-mount 4-SMD (Gull-wing) package, designed for compact circuit board layouts while maintaining robust signal transmission capabilities across isolated boundaries.
Feature Summary
- Integrates an AlGaAs LED with an NPN silicon phototransistor for efficient optical coupling
- Provides high-voltage electrical isolation rated at 5000 VRMS between input and output circuits
- Utilizes a Gull-wing surface-mount package design suitable for automated assembly processes
Applications
- Industrial control systems requiring galvanic isolation
- Signal transmission in measurement and testing equipment
- Power supply feedback loops for noise immunity
Procurement Notes
Verify the specific suffix 'F3' or 'L-A' against the manufacturer's current datasheet to confirm pinout compatibility and lead configuration. Confirm RoHS compliance status as manufacturing standards may evolve. Ensure the supplier provides valid traceability documentation for quality assurance purposes before finalizing procurement orders.
Selection Notes
Select this component when a surface-mount solution is required for high-isolation applications. Compare the collector-emitter saturation voltage and current transfer ratio against system requirements. Verify that the operating temperature range meets the environmental conditions of the target application site.
Part Context
This part belongs to the PS2501 family of optocouplers from CEL. The family includes through-hole DIP variants like the PS2501-1-W-A and other surface-mount options. These devices are widely used in industrial environments where reliable signal transfer across isolated domains is critical for system safety and performance integrity.
Replacement Considerations
Direct substitutes include the PS2501L-1-E3-L-A and PS2501L-1-A. Verify pin compatibility and electrical parameters such as CTR and isolation voltage before substitution.
