SFH601-4X017

Overview

The SFH601-4X017 is a single-channel transistor output optocoupler manufactured by Vishay Semiconductor Opto Division. It features an NPN phototransistor output with a current transfer ratio of 160% at 10 mA input current. The device provides electrical isolation with a voltage rating 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 voltage of 1.65 V at 60 mA forward current. The component operates within a temperature range of -55°C to +100°C and utilizes a surface-mount SMD package.

Feature Summary

• Provides high-voltage electrical isolation between input and output circuits for signal transmission
• Utilizes an NPN phototransistor output configuration for reliable switching applications
• Designed for through-hole or surface-mount integration depending on specific variant requirements

Applications

• Electrical isolation in communication circuits
• Signal transmission across isolated boundaries
• General-purpose optoisolation in industrial control systems

Procurement Notes

Verify the exact suffix designation when sourcing, as variants like SFH601-4 differ from SFH601-4X017 in packaging and CTR specifications. Confirm availability status as some distributors list this part as obsolete or out of stock. Ensure the selected component matches the required isolation voltage and package type for your specific PCB layout constraints before finalizing procurement orders.

Selection Notes

Select this component when a high isolation voltage of 5300 Vrms is required alongside a standard NPN phototransistor output. Consider the 160% current transfer ratio specification for driving subsequent logic stages. Evaluate the surface-mount package format against assembly capabilities. Compare performance metrics such as collector current limits and operating temperature ranges against alternative optocouplers if space or thermal constraints are critical.

Part Context

This component belongs to the SFH601 series of transistor output optocouplers from Vishay. The series includes various suffixes indicating different current transfer ratios and packaging options, such as DIP-6 tubes or SMD reels. The SFH601-4X017 specifically denotes a surface-mount variant with defined isolation characteristics, distinct from the through-hole SFH601-4 model which shares similar electrical parameters but differs in physical form factor.

Replacement Considerations
