PS2514L-1Y-A

Overview

The PS2514L-1Y-A is a high-speed switching and high isolation voltage photocoppler manufactured by CEL. It features a single channel with an NPN phototransistor output in a 4-SMD package. Key electrical parameters include a maximum collector-emitter voltage of 80 V, a forward current of 150 mA, and an isolation voltage of 5000 Vrms. The device operates within a temperature range of -55°C to +100°C, with a typical current transfer ratio of 80% at 5 mA input.

Feature Summary

• High-speed switching capability for efficient signal transmission
• High isolation voltage rating ensuring robust circuit protection
• Single-channel configuration with NPN phototransistor output

Applications

• Industrial control systems requiring galvanic isolation
• Signal isolation in microprocessor interfaces
• Power supply feedback loops

Procurement Notes

Verify the specific suffix 'L' indicates the lead-free or specific packaging variant as defined by CEL documentation. Confirm the component status, as availability may vary due to discontinuation notices from certain distributors. Ensure the 4-SMD package type matches the target PCB footprint requirements before finalizing procurement orders.

Selection Notes

Select this component when high isolation voltage and fast switching speeds are required in a compact surface-mount form factor. Compare the 80 V collector-emitter voltage and 5000 Vrms isolation against system requirements. Consider the NPN output type compatibility with downstream logic circuits and verify thermal performance within the specified operating temperature range.

Part Context

This part belongs to the PS2514 series of high-speed photocouplers from CEL. The series is designed for applications demanding reliable electrical isolation between input and output circuits. The 'L' suffix typically denotes specific manufacturing attributes such as lead-free compliance or tape-and-reel packaging, distinguishing it from standard DIP variants.

Replacement Considerations

Direct substitutes may include other CEL PS2514 series variants with compatible pinouts and electrical characteristics. Verify that any replacement maintains the 5000 Vrms isolation rating and similar switching speeds. Cross-reference datasheets to ensure package dimensions and thermal properties align with existing design constraints.
