SFH601-3X016

Overview

The SFH601-3X016 is a single-channel transistor output optocoupler manufactured by Vishay Semiconductor Opto Division. It features an NPN phototransistor with a base connection for enhanced switching speed control. The device provides 5000 Vrms isolation voltage and operates within a temperature range of -55°C to +100°C. Key electrical parameters include a maximum collector-emitter voltage of 100 V, a maximum collector current of 50 mA, and a forward current of 60 mA. The current transfer ratio ranges from 100% to 200%. It is housed in a 6-DIP package.

Feature Summary

• Integrates an NPN phototransistor with a dedicated base terminal to facilitate faster turn-off times and improved switching performance compared to standard configurations.
• Provides robust electrical isolation with a rated insulation voltage of 5000 Vrms, suitable for high-voltage noise immunity applications.

Applications

• Industrial control systems requiring galvanic isolation
• Solid-state relay driver circuits
• Signal isolation in microprocessor interfaces

Procurement Notes

Verify the specific suffix X016 corresponds to the required tube packaging configuration when ordering. Confirm that the 6-DIP footprint matches the target PCB design constraints. Ensure the 5000 Vrms isolation rating meets the safety requirements of the end application. Cross-reference the CTR range of 100-200% against circuit design margins to guarantee reliable operation across temperature variations.

Selection Notes

Select this component when base-controlled switching speed is critical for the application. The 6-DIP package offers through-hole mounting compatibility. Consider the 100 V collector-emitter voltage limit for load driving capabilities. Verify that the 150 mW power dissipation rating aligns with thermal management strategies in the final assembly.

Part Context

This part belongs to the SFH601 series of transistor output optocouplers. The X016 suffix typically denotes specific packaging or variant details within the Vishay portfolio. It serves as a general-purpose isolation device for digital signal transmission where moderate speed and high isolation are required.

Replacement Considerations

Direct substitutes may include other Vishay parts within the SFH601 series with compatible pinouts and electrical ratings. Verify equivalent CTR ranges and isolation voltages before substitution. Check for package compatibility to ensure mechanical interchangeability without PCB redesign.
