The purpose of Power Cycling is to simulate the thermal and current pulsing
stresses which devices will encounter in actual circuit applications when either the
equipment is turned on and off or power is applied to the device in short bursts
interspersed with quiescent, low power periods. The simulation is achieved by the
on/off application of power to each device while they are in the active linear
region.
The primary failure mode for power cycling is a thermal fatigue of the
silicon/metal interfaces and metal/metal interfaces.

thermal performance or degrade.
The fatigue, due to the

, will begin to increase well before any electrical effect is seen. If the
degradation occurs at the wire bond/die interface or the wire bond/post interface,
then on resistance,
V
CE(on)
, will slowly increase or become unstable with time.
The thermal impedance, when measured during this time may appear to
decrease or change erratically.
The mechanical stresses from the application of power can also propagate
fractures in the silicon when the die is thermally mismatched to the solder/heat
sink system. These fractures will manifest themselves in the form of shorted
gates or degraded breakdown characteristics (

(BR)CES
).
