Overview
The PS2501L-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 to provide electrical isolation. The device utilizes a surface-mount package configuration, specifically identified as the lead bending or gull-wing type for PCB mounting. This component is designed for applications requiring reliable signal transmission across isolated circuits while maintaining high voltage separation between input and output sides.
Feature Summary
- Integrates a GaAs LED with an NPN phototransistor for efficient optical coupling
- Provides high-voltage electrical isolation between input and output circuits
- Utilizes a surface-mount gull-wing package design for automated assembly
Applications
- Signal isolation in industrial control systems
- Interface circuits for microprocessors and logic devices
- Power supply feedback loops
Procurement Notes
Verify the specific suffix 'K-A' against official CEL documentation to confirm exact packaging and tape-and-reel specifications. Ensure the component matches the required surface-mount footprint and pin compatibility for your PCB layout. Confirm availability status directly with authorized distributors as supply levels may vary.
Selection Notes
Select this component when a surface-mount solution is required for single-channel isolation. Compare the CTR and switching speed parameters against system requirements. Ensure the operating temperature range and isolation voltage ratings meet the safety standards of the target application environment.
Part Context
This part belongs to the PS2501 series of transistor output optocouplers. The 'L' designation typically indicates a lead-bending or gull-wing surface-mount variant, distinguishing it from through-hole DIP versions like the PS2501-1. The series is widely used for general-purpose isolation tasks in electronic designs.
Replacement Considerations
Direct substitutes include other PS2501L-1 variants from CEL or equivalent single-channel NPN phototransistor optocouplers from manufacturers such as Renesas or Isocom, provided pinouts and electrical characteristics match.
