TVS transient suppression diodes can be categorized into various types based on different voltage ratings and power levels. Here are some common classification methods:
1. By working voltage rating: They can be divided into three categories: low voltage (<1.5kV), medium voltage (1.5-3kV), and high voltage (>3kV).
2. By rated power: They can be categorized into low power (<5W), medium power (5-30W), and high power (>30W).
3. By package type: They are available in various package forms such as SMD, DO-214AB, and DO-15.
4. By triggering voltage: They can be classified as unidirectional and bidirectional, with bidirectional TVS diodes further divided into symmetrical and asymmetrical types.
5. By application field: They are suited for different application scenarios such as consumer electronics, communications, and automotive electronics.
The above classification methods are only common approaches; in practice, there are other classification criteria, such as operating temperature range and reverse leakage current level. The purpose of classification is to facilitate the selection and application of different types of TVS transient suppression diodes to meet various requirements.
