SFH601-4X016

Overview

The SFH601-4X016 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 and stability. The device provides high isolation capability with a test voltage of 5300 VRMS. Key electrical parameters include a maximum collector-emitter voltage of 100 V, a maximum collector current of 100 mA, and a forward current of 60 mA. The current transfer ratio ranges from 160% to 320%. It operates within a temperature range of -55°C to +100°C and is housed in a 6-DIP package.

Feature Summary

• Integrates an NPN phototransistor with a dedicated base terminal to improve switching performance and reduce storage time.
• Provides robust electrical isolation with a high insulation test voltage rating of 5300 VRMS.
• Designed for through-hole mounting in standard DIP-6 packages for reliable circuit board integration.

Applications

• General purpose signal isolation in industrial control systems
• Interface circuits between low-voltage logic and higher voltage loads
• Power supply feedback loops requiring galvanic separation

Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels due to the presence of obsolete status indicators in some listings. Confirm that the specific suffix matches the required current transfer ratio bin. Check for RoHS compliance documentation relevant to the manufacturing date code. Ensure the DIP-6 footprint aligns with existing PCB designs before finalizing procurement orders.

Selection Notes

Select this component when high isolation voltage and fast switching are required in a single-channel configuration. The base-connected phototransistor offers superior performance over standard variants for applications demanding rapid turn-off times. Consider the 100 V collector voltage limit and 100 mA current capacity against load requirements. Evaluate the 5300 VRMS isolation barrier for safety-critical designs.

Part Context

This part belongs to the SFH601 series of Vishay's transistor output optocouplers. The series is characterized by its base-connected phototransistor architecture, which distinguishes it from standard phototransistor outputs. The SFH601-4X016 specifically denotes the 160-320% CTR bin within the DIP-6 package family.

Replacement Considerations

SFH601-1X016 (CTR 40-80%), SFH601-3 (CTR 100-200%). Verify CTR requirements and pin compatibility when substituting.
