PS2561L1-1-V

Overview

The PS2561L1-1-V is a single-channel transistor output optocoupler manufactured by CEL. It features an NPN phototransistor output and provides high isolation voltage of 5000 Vrms. The device operates with a maximum collector-emitter voltage of 80 V and supports a forward current of up to 10 mA. It is housed in a 4-DIP package with a pin spacing of 10.16 mm. The component is designed for through-hole mounting and functions within a temperature range of -55°C to +100°C.

Feature Summary

• Provides high electrical isolation between input and output circuits
• Utilizes an NPN phototransistor for signal transmission
• Designed for direct coupling with logic circuits

Applications

• Industrial control systems
• Power supply feedback loops
• Signal isolation in measurement equipment

Procurement Notes

Verify the specific suffix (e.g., -A, -F3) against official datasheets to confirm packaging and compliance details. Confirm availability status as some variants may be discontinued or restricted. Ensure the selected part matches the required insulation voltage and operating temperature range for the target application environment.

Selection Notes

Select this component when high isolation voltage is required for single-channel signal transfer. Compare the NPN phototransistor output characteristics against alternative Darlington outputs if higher gain is needed. Verify that the 80 V collector-emitter voltage rating meets the load requirements of the receiving circuit.
