PS2514-1Y-A

Overview

The PS2514-1Y-A is a photovoltaic output optoisolator manufactured by CEL, featuring a single channel with a 5000Vrms isolation voltage. It utilizes a 4-DIP package and incorporates a Darlington transistor output configuration. The device is designed for high-speed switching applications, offering a guaranteed maximum turn-off time of 25 μs at 5mA input current. It supports a collector-to-emitter voltage of 40V and operates within a standard temperature range. This component provides robust electrical isolation for signal transmission between circuits.

Feature Summary

• High isolation voltage capability of 5000Vrms for safe circuit separation
• Guaranteed fast switching speed with a maximum turn-off time of 25 μs
• Darlington transistor output structure for high gain and sensitivity
• Halogen-free and lead-free construction compliant with environmental standards

Applications

• Industrial control systems requiring galvanic isolation
• Power supply feedback loops for voltage regulation
• Microcontroller interface circuits for noise immunity
• Solid-state relay driver stages

Procurement Notes

Verify the specific suffix 'Y-A' to confirm halogen-free and lead-free status, as these attributes are critical for compliance. Confirm the manufacturer origin, as CEL products may be sourced from Renesas Electronics Corporation. Ensure the package type matches the required 4-DIP footprint for PCB integration. Check for any updated safety certifications such as UL, CSA, or CQC if required for end-product approval.

Selection Notes

Select this component when high isolation voltage and fast switching are required in a compact DIP package. The Darlington output offers higher current transfer ratio compared to standard transistor outputs. Consider the 40V collector-emitter voltage rating for load compatibility. Verify that the 25 μs turn-off time meets the system's timing constraints. Ensure the operating temperature range aligns with the application environment.

Part Context

The PS2514 series belongs to a family of high-isolation voltage photocouplers designed for reliable signal transmission. The PS2514-1Y-A variant specifically denotes the halogen-free and lead-free version of the standard PS2514-1. These devices are widely used in industrial and consumer electronics where safety isolation is mandated. The series is known for its consistent performance and adherence to international safety standards.

Replacement Considerations

Direct substitutes include the PS2514L-1Y-A for halogen-free variants. The PS2514-1-V-A may be considered for voltage-rated equivalents. Verify pinout compatibility and isolation voltage ratings before substitution. Cross-reference with Renesas datasheets for equivalent part numbers in the PS2514 family.
