The SFH6139-X017T is a Vishay Semiconductor Opto Division phototransistor output optocoupler featuring surface mount packaging. It provides 5300 VRMS insulation voltage and supports an operating temperature range of -55°C to 100°C. The device has a maximum DC forward current of 20mA and utilizes a gull-wing SMD package for board mounting.
Verify the specific suffix against official Vishay documentation to confirm pinout compatibility and lead frame material. Ensure the component matches the required thermal dissipation characteristics for the intended application environment before finalizing procurement orders.
Select this component when high isolation voltage and robust transient immunity are required in a compact surface mount form factor. Consider the 20mA forward current limit and the specific current transfer ratio requirements relative to the load driving capabilities of the target circuit design.
This part belongs to the SFH6139 family of Vishay optocouplers, designed for applications demanding reliable electrical isolation between input and output circuits. The X017T suffix typically denotes specific tape and reel packaging configurations for automated assembly processes.
