Diode Ratings and Characteristics
Absolute maximum ratings and electrical characteristics are described in the data sheet. This section describes the ratings and characteristics described in our data sheet.
Absolute Maximum Ratings
The absolute maximum ratings are allowable values that should not be exceeded even instantaneously. If the values are exceeded, the semiconductor may be damaged. Therefore, it is required to design electronic devices that use semiconductors so that stress exceeding the values is not applied to semiconductors even instantaneously.
Absolute maximum ratings do not guarantee reliability. Even within the absolute maximum ratings, if the recommended conditions are exceeded, their durability decreases and as a result, semiconductors may not withstand long-term use.
The parameters specified in the absolute maximum ratings are listed below. The parameters of absolute maximum ratings listed depend on the diode type.
