    Hello All,

    Can anybody tell about manufacturer of TVS diode mentioned in Image?

    It looks like Vishay Semiconductor , but it is not. Attached second image which consists both diode images.
    First diode is Vishay (3.3V TVS). Second diode is unknown manufacturer , still claiming 3.3V TVS.

    Thank you in advance.
    Srinivas

    One is General Semiconductor - split off from the old General Instrument many years ago. General Semi made Transorbs and other TVS stuff. Now owned by Vishay.

    The left one in the picture looks legitimate. The right one kind of looks like a fake, actually.
