**Cause: 1. *OverheatingOverheating is one of the Thermal Runaway*
**Cause: common causes of failure in MOSFThe most common failure point in thes. The FDD5614DD5614P is overheating., like other MOSFETs occurs when the transistor is subjected to can fail due to excessive power diss power dissipation or when the circuit, often caused by improper heat sinking not provide adequate cooling. Overhe overcurrent conditions. Inadequate can lead to thermal runaway, where can lead to a rise in junction increase in temperature causes a further increase, which can exceed the maximum rated current, eventually destroying the component.
