SFH615AY-X018T

Overview

The SFH615AY-X018T is a single-channel transistor output optocoupler manufactured by Vishay Semiconductor Opto Division. It integrates an infrared LED and an NPN phototransistor in a surface-mount package to provide electrical isolation between input and output circuits. Key electrical parameters include a maximum collector-emitter voltage of 70 V, a maximum collector current of 50 mA, and a forward current of 60 mA. The device offers a typical forward voltage of 1.35 V at the specified test conditions. Isolation performance is rated at 5300 Vrms. The component operates within a temperature range of -55°C to +100°C.

Feature Summary

Provides high-voltage electrical isolation between input and output circuits using an infrared LED and phototransistor pair.
Designed for signal transmission and impedance transformation in digital logic applications.
Features a surface-mount gull-wing package suitable for automated assembly processes.

Applications

Digital logic signal transmission and level shifting
Power supply control and switching circuits
Electrical insulation isolation between circuit stages or systems

Procurement Notes

Verify the specific suffix X018T against the manufacturer's datasheet to confirm the exact Current Transfer Ratio (CTR) binning and packaging configuration. Ensure the ordering part number matches the required lead frame finish and reel specifications for surface mount assembly. Cross-reference with official Vishay documentation to validate RoHS compliance status and recommended soldering profiles.

Selection Notes

Select this component when a surface-mount solution is required for single-channel isolation with a 5300 Vrms rating. Compare the CTR range of 50% to 150% against circuit gain requirements. Consider the 50 mA collector current limit and 70 V breakdown voltage for load compatibility. Evaluate the thermal dissipation capabilities within the specified operating temperature range during design integration.

Part Context

This part belongs to the SFH615A series of transistor output optocouplers from Vishay. The series includes through-hole variants like the SFH615A-2X016 and other surface-mount options such as the SFH615AY-X008T. These devices share similar core isolation technologies but differ in package type, mounting style, and specific CTR grading bins defined by their alphanumeric suffixes.

Replacement Considerations

The VO615A-1X001 is listed as a recommended alternative in related product data. Verify pinout compatibility and electrical parameter overlaps before substitution. Note that the VO615A typically features a DIP-4 through-hole package, requiring mechanical redesign if replacing the SMD SFH615AY-X018T.
