4N25-X006

Overview

The Vishay 4N25-X006 is a single-channel transistor output optocoupler featuring an NPN phototransistor. It provides 5000 Vrms isolation voltage and operates within a temperature range of -55°C to +100°C. Key electrical parameters include a minimum current transfer ratio (CTR) of 20%, a maximum collector-emitter voltage of 70 V, and a maximum collector current of 50 mA. The device utilizes a DIP-6 through-hole package.

Feature Summary

• Provides high-voltage isolation between input and output circuits
• Features a standard industry dual-in-line 6-pin package
• Utilizes gallium arsenide infrared LED coupled with silicon NPN phototransistor

Applications

• Logic ground isolation
• Switch mode power supply feedback
• Telephone ring detection

Procurement Notes

Verify the specific suffix against official Vishay documentation to confirm package type and compliance status. Ensure the procurement channel sources directly from authorized distributors or the manufacturer to guarantee component authenticity and traceability for industrial applications.

Selection Notes

Select this component when a robust, general-purpose optocoupler with high isolation voltage is required. The DIP-6 form factor supports through-hole mounting, making it suitable for legacy designs or applications requiring mechanical stability in high-vibration environments compared to surface-mount alternatives.

Part Context

This part belongs to the Vishay 4N2x series of single-channel phototransistor optocouplers. These devices are designed for general-purpose signal isolation and switching applications.
