SFH601-4X001

Overview

The SFH601-4X001 is a single-channel phototransistor 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 high isolation capability with a test voltage of 5300 Vrms 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 100 mA, and a forward voltage of 1.65 V at 60 mA forward current. The current transfer ratio (CTR) ranges from 160% to 320%. The component is housed in a DIP-6 package and has a power dissipation rating of 150 mW.

Feature Summary

• High isolation voltage rating of 5300 Vrms for robust circuit protection
• Phototransistor output with base connection allowing for improved switching performance
• Wide operating temperature range suitable for demanding industrial environments

Applications

• Industrial automation control systems
• Power supply feedback loops
• Signal isolation in measurement equipment

Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels due to the presence of obsolete status indicators in some listings. Confirm RoHS compliance status as specified in the official datasheet before integration. Ensure that the specific suffix X001 matches the required packaging and binning specifications for the intended production run. Cross-reference the part number against the latest Vishay product change notifications to confirm current manufacturing status and availability constraints.

Selection Notes

Select this component when high isolation voltage and fast switching are required in a through-hole configuration. The base connection feature distinguishes it from standard phototransistor optocouplers by offering better control over storage time. Consider the 160-320% CTR range for signal amplification requirements. Evaluate the DIP-6 package compatibility with existing PCB footprints. Compare against similar Vishay series parts if higher channel counts or different output types are needed.

Part Context

The SFH601 series belongs to Vishay's family of phototransistor output optocouplers designed for general-purpose isolation applications. The SFH601-4 variant specifically denotes a particular Current Transfer Ratio (CTR) bin within the series. This series is characterized by its robust insulation properties and suitability for replacing older electromechanical relays in compact electronic designs. The X001 suffix typically indicates specific packaging or testing configurations defined by the manufacturer.
