SFH601-2X017

Overview

The SFH601-2X017 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 noise immunity. The device provides high isolation voltage of 5300 Vrms, suitable for demanding industrial applications. Key electrical parameters include a maximum collector-emitter voltage of 100 V, a maximum collector current of 100 mA, and a power dissipation of 150 mW. The forward voltage is typically 1.65 V at a forward current of 60 mA. The unit operates within a temperature range of -55°C to +100°C and is housed in a 6-SMD surface-mount package.

Feature Summary

• Integrated base connection on the phototransistor output to improve switching characteristics and reduce storage time.
• High insulation voltage capability of 5300 Vrms ensuring robust galvanic isolation between input and output circuits.
• Surface-mount 6-SMD packaging designed for automated assembly and compact circuit board layouts.

Applications

• Industrial control systems requiring reliable signal isolation
• Solid-state relay driver circuits
• Microcontroller interface isolation

Procurement Notes

Verify the specific suffix X017 against the manufacturer's latest datasheet to confirm pinout configuration and tape-and-reel specifications. Ensure that the 6-SMD footprint matches the design layout. Cross-reference the component marking with official Vishay identification guides to prevent counterfeit substitution during procurement.

Selection Notes

Select this component when high-speed switching performance is critical due to the integrated base terminal. Compare the 5300 Vrms isolation rating against system safety requirements. Evaluate the 100 mA collector current limit against load demands. Consider the surface-mount form factor for space-constrained designs compared to through-hole alternatives.

Part Context

This part belongs to the SFH601 series of Vishay optocouplers, which are characterized by phototransistor outputs with base connections. The series offers variants with different packaging options, including DIP and SMD configurations. These devices are engineered for general-purpose isolation tasks where standard phototransistor response times may be insufficient.

Replacement Considerations

Direct substitutes include SFH601-2X017T and SFH601-2X016. Verify pin compatibility and isolation ratings before substitution. Generic replacements must match the 6-SMD package and NPN phototransistor output type.
