Description

technical field

[0001] The invention relates to the technical field of semiconductor devices, in particular to a two-piece frame of a TVS diode. Background technique

[0002] TVS diode, also known as transient suppression diode, is a new type of high-efficiency circuit protection device commonly used. It has extremely fast response time (sub-nanosecond level) and relatively high surge absorption capacity. When its two ends are subjected to instantaneous high-energy impact, TVS can change the impedance value between the two ends from high impedance to low impedance at a very high speed, so as to absorb an instantaneous large current and clamp the voltage at both ends A predetermined value, so as to protect the subsequent circuit components from the impact of transient high-voltage spikes.

[0003] As a protective device in the circuit, the quality of TVS diodes is particularly important. At present, during the production process of TVS diodes, the stress generated in the pr...

Embodiment Construction

[0027] The present invention will be further described below in conjunction with the accompanying drawings. The TVS diode frame assembly includes an upper frame assembly 1 and a lower frame assembly 2. The lower frame assembly 2 includes an upper edge 231 of the lower frame, a lower edge 232 of the lower frame, and is connected to the upper edge 231 and the lower edge of the lower frame. Some lower frame ribs 22 between the lower frame ribs 232 are evenly distributed with some lower frame units 21 on both sides of the lower frame ribs 22; the upper frame assembly 1 includes upper frame upper edge 131, upper frame lower edge 132, and is connected An upper frame rib 12 on the upper edge 131 and the lower edge 132 of the upper frame; several upper frame units 11 are evenly distributed on both sides of the upper frame rib 12; when the upper frame assembly 1 is superimposed on the lower frame assembly 2, the lower frame unit 21 and the upper The frame units 11 are aligned one by one...
