PTC

    PTC (Power and Temperature Cycling)

    • It is applied to semiconductor devices that need to be turned on or off through a specific temperature.
    • Evaluate resistance by repeatedly exposing the device to low and high temperatures and by periodically giving or removing the operating bias.

    Conditions of progress

    Condition Reference Test requirements/cautions
    Power Temperature Cycling JEDEC JESD22-A105 Grade 0 : Ta of -40ºC to +150ºC for 1000 cycles.
    Grade 1 : Ta of -40ºC to +125ºC for 1000 cycles.
    Grades 2 and 3 : Ta -40ºC to +105ºC for 1000 cycles.
    • It is not necessary to synchronize the power cycle with the temperature cycle.
