Overview
The CEL PS2503-1-K-A is a single-channel transistor output optoisolator designed for electrical isolation between circuits. It features an NPN phototransistor output and operates with a forward current of up to 80 mA and a forward voltage of 1.4 V. The device provides a high insulation voltage of 5000 Vrms, ensuring robust signal transfer across isolated domains. Key electrical parameters include a maximum collector-emitter voltage of 80 V, a maximum collector current of 50 mA, and a power dissipation rating of 120 mW. It functions within a temperature range of -55°C to +100°C and is housed in a standard 4-DIP package.
Feature Summary
- Provides reliable electrical isolation between input and output circuits using a transistor output configuration.
- Designed for low input current operation combined with high-speed switching capabilities.
- Ensures safety through a high insulation voltage rating suitable for AC input applications.
Applications
- Embedded systems requiring circuit isolation
- AC input detection interfaces
- Signal transmission across isolated grounds
