Overview
The PS2501L-1 is a single-channel transistor output optocoupler manufactured by CEL. It integrates a Gallium Arsenide (GaAs) infrared emitting diode with an NPN silicon phototransistor to provide electrical isolation. The device features a high isolation voltage of 5000 Vrms and supports a collector-emitter voltage of up to 80 V. Designed for through-hole mounting, it utilizes a standard DIP-4 package configuration. The component operates within a temperature range of -55°C to +100°C, ensuring reliability in various industrial environments.
Feature Summary
- Integrates a GaAs LED with an NPN phototransistor for efficient optical coupling
- Provides high-voltage electrical isolation between input and output circuits
- Supports fast switching speeds suitable for digital signal transmission
Applications
- Industrial control systems requiring signal isolation
- Power supply feedback loops for voltage regulation
- Microcontroller interface circuits for noise immunity
Procurement Notes
Verify the specific suffix codes against official datasheets to confirm pinout compatibility and insulation class. Confirm that the procurement source provides authentic components from CEL or authorized distributors. Check for RoHS compliance status if required by your manufacturing standards. Ensure the package type matches your PCB footprint requirements before ordering.
Selection Notes
Select this component when high isolation voltage and moderate speed are required for single-channel applications. Compare the collector-emitter saturation voltage and current transfer ratio against circuit load requirements. Consider the operating temperature range to ensure performance stability under environmental stress. Verify package dimensions against available board space constraints.
Part Context
This part belongs to the PS2501 series of optically coupled isolators. The series includes variants such as PS2501-1, PS2501-4, and PS2501L-1. These devices share common architectural features including GaAs LEDs and NPN phototransistors. The 'L' designation typically indicates a specific lead form or packaging variation within the family.
Replacement Considerations
Cross-reference with PS2501-1-W-A for equivalent functionality. Verify pinout alignment and isolation voltage ratings before substitution. Ensure thermal characteristics match the original design specifications.
