Overview
The PS2561AL-1-N-A is a single-channel transistor output optocoupler manufactured by Renesas Electronics. It features an NPN phototransistor output housed in a DIP-4 Gull Wing package. Key electrical parameters include a maximum collector-emitter voltage of 70 V, a maximum collector current of 30 mA, and a forward voltage of 1.2 V at a forward current of 10 mA. The device provides 5000 Vrms insulation voltage and operates within a temperature range of -55°C to +100°C. Switching characteristics specify a rise time of 3 µs and a fall time of 5 µs.
Feature Summary
- Provides galvanic isolation between input and output circuits using optical transmission.
- Features an NPN phototransistor output for digital signal switching applications.
- Designed with high insulation voltage capability for safety-critical interfaces.
Applications
- Industrial control systems requiring signal isolation
- Power supply feedback loops
- Microcontroller interface circuits
Procurement Notes
Verify component status as the PS2561AL-1-N-A is listed as discontinued or not recommended for new designs in some sources. Confirm availability through authorized distributors or secondary markets. Ensure replacement strategies are evaluated if long-term supply stability is required for production. Check RoHS compliance details on official datasheets before integration.
Selection Notes
Select this component for applications requiring a single-channel transistor output with moderate speed and high isolation voltage. Compare CTR specifications against load requirements. Consider package compatibility with existing PCB layouts. Evaluate thermal performance within the specified operating temperature range. Verify that the 70 V collector-emitter voltage meets circuit design margins.
