SFH615AY-X019

Overview

The SFH615AY-X019 is a single-channel photovoltaic output optoisolator manufactured by Vishay Semiconductor Opto Division. It features a gallium arsenide infrared LED coupled to a silicon photovoltaic detector, providing high electrical isolation with an insulation voltage of 5300 Vrms. The device utilizes a surface-mount 4-SMD (Gull Wing) package suitable for automated assembly. Key electrical characteristics include a maximum collector-emitter saturation voltage of 400 mV and a power dissipation rating of 150 mW. It operates within a temperature range of -55°C to +100°C and supports a forward current of 60 mA.

Feature Summary

Photovoltaic output architecture generates open-circuit voltage without external bias
High dielectric isolation strength between input and output circuits
Surface-mount gull-wing package design for reliable PCB integration

Applications

DC input signal isolation in industrial control systems
Gate drive isolation for power switching devices
Signal transmission across isolated boundaries in measurement equipment

Procurement Notes

Verify the specific suffix designation against the manufacturer's official datasheet to confirm the photovoltaic output configuration and package type. Ensure that the procurement documentation explicitly references the SFH615AY-X019 part number to distinguish it from transistor-output variants within the same family. Confirm compliance with relevant safety standards required for the intended application environment.

Selection Notes

Select this component when a zero-bias voltage output is required for galvanic isolation. The photovoltaic nature eliminates the need for a pull-up resistor on the output side, simplifying circuit design. Consider the 5300 Vrms isolation rating for applications requiring robust separation between high-voltage and low-voltage domains. Evaluate the surface-mount form factor against available board space constraints.

Part Context

This component belongs to the SFH615A series of optocouplers, which are designed for general-purpose isolation applications. The 'Y' suffix typically denotes a specific tape-and-reel packaging option or variant within the product line. Vishay Semiconductor Opto Division produces this series to meet demands for compact, high-isolation optoelectronic solutions in modern electronic designs.
