Overview

The SFH615A-2X017 is a single-channel transistor output optocoupler manufactured by Vishay Semiconductor Opto Division. It features an NPN phototransistor output with a maximum collector current of 50 mA and a collector-emitter voltage rating of 70 V. The device provides high isolation capability with a rated insulation voltage of 5300 Vrms. Key electrical parameters include a forward voltage of 1.65 V at a maximum forward current of 60 mA, and a power dissipation limit of 150 mW. The unit operates within a temperature range of -55°C to +100°C and utilizes a 4-SMD surface-mount package.

Feature Summary

• Provides robust electrical isolation with a 5300 Vrms insulation voltage rating for safe signal transmission between isolated circuits.
• Features a fast switching response with typical rise and fall times of 3 µs and 14 µs respectively, suitable for moderate-speed digital applications.
• Delivers high current transfer efficiency with a CTR range of 63% to 125%, ensuring reliable output activation across varying conditions.

Applications

• Industrial control systems requiring galvanic isolation
• Signal interfacing in measurement and testing equipment
• Power supply feedback loops for voltage regulation

Procurement Notes

Verify the specific suffix code '2X017' against official Vishay documentation to confirm the exact Current Transfer Ratio binning and packaging configuration. Ensure that the procurement source provides valid traceability and authenticity certificates, as optical characteristics can vary significantly between different manufacturing lots and binning categories. Cross-reference the datasheet revision date to ensure compliance with current safety standards.

Selection Notes

Select this component when a surface-mount solution is required for high-voltage isolation applications. The 63-125% CTR range offers flexibility for driving standard logic inputs without excessive input current. Consider the 4-SMD footprint constraints during PCB layout design. Compare against through-hole alternatives if higher thermal mass or mechanical robustness is prioritized over board space efficiency.

Part Context

This part belongs to the SFH615A series of transistor output optocouplers from Vishay. The series is designed for general-purpose isolation tasks, offering a balance of speed and sensitivity. The '2X017' designation specifically indicates the SMD package variant with defined CTR performance bins, distinguishing it from DIP versions like the SFH615A-1 or other SMD variants with different binning codes.
