SFH1617A-2X017T

Overview

The SFH1617A-2X017T is a single-channel transistor output optocoupler manufactured by Vishay Semiconductor Opto Division. It features an NPN phototransistor output and operates within a temperature range of -55°C to +110°C. Key electrical parameters include a maximum collector-emitter voltage of 70 V, a maximum collector current of 50 mA, and a power dissipation of 150 mW. The device provides an isolation voltage of 5000 Vrms with a typical forward voltage of 1.65 V at a maximum forward current of 60 mA. The current transfer ratio ranges from 63% to 125%. Timing characteristics specify a rise time of 3 µs and a fall time of 14 µs. The component utilizes a 4-SMD surface-mount package.

Feature Summary

• Provides high-voltage electrical isolation between input and output circuits via optical coupling.
• Features a fast switching response suitable for digital signal transmission applications.
• Designed for robust operation across extended industrial temperature ranges.

Applications

• Industrial control systems requiring galvanic isolation
• Communication equipment signal interfacing
• Power supply feedback loops

Procurement Notes

Verify the specific suffix X017T corresponds to the Tape & Reel packaging configuration when ordering. Confirm that the 4-SMD footprint matches the target PCB design constraints. Ensure the selected variant meets the required insulation voltage standards for the intended safety application. Cross-reference the manufacturer datasheet for any recent product change notices affecting specifications or compliance status.

Selection Notes

Select this component when a single-channel transistor output is required with moderate speed capabilities. The 5000 Vrms isolation rating supports high-noise environments. Consider the 63-125% CTR range for biasing calculations. The wide operating temperature range makes it suitable for harsh conditions. Verify that the 4-SMD package aligns with automated assembly requirements.

Part Context

This part belongs to the SFH1617A series of transistor output optocouplers. It shares functional similarities with other Vishay devices in the same family but differs in packaging and specific electrical tolerances. The X017T suffix indicates a specific reel-based packaging option distinct from tube-packaged variants like the SFH1617A-2.
