SFH615A-1X017T

Overview

The SFH615A-1X017T is a single-channel transistor output optocoupler manufactured by Vishay Semiconductor Opto Division. It features an NPN phototransistor output and operates in a 4-SMD gull-wing package. Key electrical parameters include a maximum collector-emitter voltage of 70 V, a maximum collector current of 50 mA, and an isolation voltage of 5300 Vrms. The device supports a forward current of 60 mA with a typical forward voltage of 1.35 V to 1.65 V. Current transfer ratio ranges from 40% to 80%, with saturation voltage up to 400 mV. Switching characteristics include rise times of 2 µs and fall times between 2 µs and 11 µs. Operating temperature spans -55°C to +100°C.

Feature Summary

• Provides high-voltage electrical isolation via infrared LED and NPN phototransistor interface
• Designed for surface-mount assembly using a compact 4-SMD gull-wing footprint
• Offers fast switching performance suitable for digital signal transmission applications

Applications

• Digital signal isolation in industrial control systems
• Interface circuits for microcontrollers and logic families
• Power supply feedback loops requiring galvanic isolation

Procurement Notes

Verify the specific suffix '1X017T' confirms the tape and reel packaging format, as standard variants may differ. Confirm the manufacturer is Vishay Semiconductor Opto Division to ensure component authenticity. Cross-reference the datasheet for exact thermal dissipation limits and soldering profiles compatible with the SMD gull-wing package before integration into production lines.

Selection Notes

Select this component when a surface-mount solution with 5300 Vrms isolation is required. Ensure the 70 V collector-emitter voltage rating exceeds the load requirements. Verify that the 40-80% current transfer ratio meets the drive capability needs for the connected circuitry. Consider the operating temperature range of -55°C to +100°C for environmental compatibility.

Part Context

This part belongs to the SFH615A series of transistor output optocouplers. It serves as a surface-mount alternative to through-hole DIP packages like the VO615A. The series is designed for general-purpose isolation tasks where compact board space and automated assembly are priorities. It shares functional similarities with other Vishay optocouplers but differs in package type and specific electrical tolerances.

Replacement Considerations

The VO615A-1X001 is listed as a recommended alternative, though it utilizes a through-hole DIP-4 package rather than SMD. Direct pin-to-pin replacement requires verifying package compatibility. Other equivalents may exist within the same family, but electrical parameters such as CTR and isolation voltage must be matched.
