Description

technical field [0001] The invention relates to a DO-13 transient voltage suppression diode. Background technique [0002] Low-capacitance transient voltage suppression diode is a kind of precision components in electronic circuits that can not only protect the damage of various surge pulses, but also avoid the large junction capacitance of ordinary transient voltage suppression diodes in high-frequency electronic circuit applications. New semiconductor discrete devices with signal distortion problems are widely used in various fields such as electronic instruments, precision equipment, automatic control systems, computer systems, and CNC machine tools. At present, a low-capacitance silicon transient voltage suppression diode in a D0-13 metal package on the market not only has the significant advantages of low junction capacitance, but also has the advantages of small size, light weight, low manufacturing cost, and high reliability. However, for the ultra-low capacitance (l...
