läpimenojännitte

Läpimenojännite, sometimes translated as breakdown voltage, is a critical parameter for electrical insulation and semiconductor devices. It represents the maximum voltage that can be applied across an insulating material or a component before it loses its insulating properties and begins to conduct electricity. This transition from insulation to conduction is often sudden and can be accompanied by significant current flow, potentially leading to device failure or damage.

The läpimenojännite is dependent on several factors, including the type of insulating material, its thickness, temperature, and the presence of impurities or defects. For dielectric materials, exceeding the läpimenojännite can cause irreversible breakdown. In semiconductor devices like diodes, the läpimenojännite (often referred to as reverse breakdown voltage) is a characteristic that determines the device's operational limits in reverse bias. Exceeding this voltage can lead to a rapid increase in reverse current.

Understanding and controlling the läpimenojännite is essential in the design and application of electrical and electronic components to ensure reliability and prevent catastrophic failures. It is a key specification for selecting appropriate insulating materials and for operating semiconductor devices within their safe limits.
