    Dear Sir,

    i have use L298 drive IC for stepper motor(1A,24VDC) using microcontroller IC.
    When i can connect the motor to driver after 1 to 3 sec driver IC damage without heating. (The upper transistor of winding O3 has been shorted)
    I have use fast recovery diode as UF-4005.

    Your schematic did not attach.

    You should also provide your stepper motors' manufacturer name and part number.
