    Hi Jerry,

    These transistors should not be damaged by overcurrents. The device has internal current limiting that prevents the output current from increasing beyond 250 mA. This amount of current results in heating of the device, but above a certain threshold (170 C) the output will be disabled (made high-impedance) in order to reduce power dissipation and protect from damage.

    Regards,
    Max
