PS2514-1Y-A

Overview

The PS2514-1Y-A is a single-channel DC input photocoupler manufactured by Renesas Electronics Corporation. It features a transistor output configuration housed in a 4-DIP package with a 0.300-inch (7.62mm) width. The device provides a high isolation voltage of 5000Vrms and maintains a minimum creepage distance of 7mm. Key electrical parameters include a maximum forward current of 30mA, a typical forward voltage of 1.1V, and an output voltage rating of 40V. The collector-emitter saturation voltage is limited to 350mV, while the output channel can handle up to 20mA. The current transfer ratio ranges from 50% to 200% at a forward current of 5mA. Switching characteristics are defined by typical rise and fall times of 15µs each. The component operates within a temperature range of -55°C to 100°C.

Feature Summary

• Provides galvanic isolation between circuits using a high-voltage optoisolator design.
• Features a transistor output stage suitable for digital signal transmission.
• Designed for high-speed switching applications with specified rise and fall times.

Applications

• General-purpose digital signal isolation

Procurement Notes

Verify the specific suffix against official Renesas documentation to confirm package type and tape/reel specifications. Ensure the procurement source provides valid RoHS compliance data and confirms the active status of the part number. Cross-reference the manufacturer product number with authorized distributor catalogs to avoid counterfeit components. Confirm that the delivery lead time aligns with project schedules, as standard lead times may vary based on manufacturing availability.

Selection Notes

Select this component when a single-channel isolation barrier is required with a DIP footprint. The 5000Vrms isolation rating supports safety standards for mains-connected equipment. The transistor output is appropriate for logic-level interfacing where moderate speed is sufficient. Consider the 7mm creepage distance for PCB layout clearance requirements. Evaluate the 15µs switching speed against system timing constraints before finalizing the design.
