VO617A-3X018T is listed in the Transistor, Photovoltaic Output Optoisolators range at ChipApex. The manufacturer field lists Vishay Semiconductor Opto Division. Its product description is OPTOISOLTR 5.3KV 1CH TRANS 4-SMD. Review the specifications below when checking this part for your BOM.
The VO617A-3X018T is a single-channel transistor output optocoupler from Vishay, designed for automotive applications. It features a wide-body SMD package with high isolation voltage of 5300 VRMS. The device supports a maximum collector-emitter voltage of 80V and a continuous collector current of 50mA. Typical forward voltage is 1.34V at a maximum DC forward current of 50mA. The saturation voltage is limited to 400mV. Operating temperature ranges from -55°C to +110°C.
Verify the specific suffix X018T corresponds to the required tape and reel packaging configuration. Confirm that the component meets the necessary automotive qualification standards for the intended application environment. Ensure compatibility with surface-mount assembly processes given the wide-body SMD form factor.
Select this component when high isolation voltage and automotive certification are required in a compact surface-mount footprint. Consider the 50mA output current limit and 80V voltage rating for circuit design constraints. Evaluate thermal management requirements within the specified -55°C to +110°C operating range.
This part belongs to the VO617A series of transistor output optocouplers. It shares functional similarities with through-hole variants like VO617A-3 but offers a surface-mount solution. The series is characterized by high CTR and robust isolation performance for industrial and automotive use cases.
Direct substitutes include VO617A-3X016T for similar specifications in different packaging. Cross-reference SFH617A-3 for through-hole equivalents. Verify pinout and electrical parameters before substitution.
