Overview
The PS2505L-1-A is a single-channel transistor output optocoupler manufactured by CEL. It integrates a Gallium Arsenide (GaAs) infrared emitting diode with an NPN silicon phototransistor for signal isolation. The device provides high insulation voltage of 5000 Vrms, suitable for AC input response applications. Key electrical parameters include a maximum collector-emitter voltage of 80 V and a maximum collector current of 50 mA. The forward voltage is typically 1.4 V at 80 mA forward current. Power dissipation is rated at 120 mW. Operating temperature range spans from -55°C to +100°C. The component is available in a surface-mount package configuration.
Feature Summary
- Integrates GaAs LED with NPN phototransistor for optical isolation
- Provides high insulation voltage capability for safety isolation
- Designed for AC input response applications
- Supports wide operating temperature range
Applications
- AC input detection circuits
- Signal isolation in industrial control systems
- Power supply feedback loops
- Microcontroller interface isolation
Procurement Notes
Verify availability status as the component may be discontinued or restricted. Confirm RoHS compliance details through official datasheets. Check for alternative sourcing channels if direct manufacturer supply is unavailable. Ensure packaging specifications match design requirements. Validate technical parameters against specific application needs before procurement.
Selection Notes
Consider channel count requirements; this model offers single-channel isolation. Evaluate insulation voltage needs against system safety standards. Assess thermal management capabilities given the power dissipation rating. Verify package compatibility with PCB layout constraints. Compare performance characteristics with similar multi-channel options if space allows.
Part Context
This part belongs to the PS2505L series of high isolation voltage photocouplers. The series includes variants with different channel counts and package types. CEL manufactures these components for reliable signal transmission across isolated boundaries. The product line targets applications requiring robust electrical isolation between low-voltage control circuits and higher-voltage power sections.
Replacement Considerations
PS2505L-1-E3: Previous generation variant with similar specifications. PS2505L-1-F3: Alternative version within the same family. PS2505-1: Non-L version with potentially different mounting style. Verify pinout compatibility and parameter equivalence before substitution.
