PS2501L-1-K-A

Overview

The PS2501L-1-K-A is a high-voltage optoisolator manufactured by Renesas Electronics Corporation. It features a single channel with an NPN silicon phototransistor output and a GaAs LED input. The device provides a 5000Vrms isolation voltage rating. Key electrical parameters include a maximum collector-emitter voltage of 80V, a collector current of 50mA, and a typical rise/fall time of 3µs/5µs. The component operates within a temperature range of -55°C to +100°C.

Feature Summary

• Provides high-voltage electrical isolation between input and output circuits
• Utilizes a GaAs light emitting diode for efficient optical coupling
• Features an NPN silicon phototransistor for reliable signal transmission

Applications

• Industrial control systems requiring galvanic isolation
• Power supply feedback loops
• Microcontroller interface circuits

Procurement Notes

Verify the specific suffix 'K' against official Renesas documentation to confirm package type and tape/reel specifications, as standard listings may vary. Confirm RoHS compliance status through the manufacturer's latest certification documents before procurement.

Selection Notes

Select this component when a single-channel transistor output isolator with 5000Vrms capability is required. Ensure the 80V collector-emitter voltage and 50mA output current meet the load requirements. Verify that the SMD packaging aligns with the PCB design constraints.

Part Context

This part belongs to the PS2501 family of optocouplers from Renesas. It shares core functional characteristics with variants like PS2501L-1-A but may differ in packaging or reel configuration due to the 'K' suffix. It is designed for general-purpose isolation applications.

Replacement Considerations

PS2501L-1-A is a direct functional equivalent within the same series. Verify pinout compatibility and ensure the replacement matches the required isolation voltage and current transfer ratio specifications.
