power of a TVS diode can be a few watts for small signal circuit protection to several
thousand watts for power panel protection. ATVS that handles large currents will also
have large capacitance due to geometry, which could be 500 pF to 10 nF, limiting their
application for high-frequency signals [1]. One method to reduce this capacitance
would be to use suppressor diodes in series with forward-biased switching diodes
to effectively reduce the shunt capacitance. Preserving bipolar clamping, two techniques
for reducing the capacitance are shown in Figure 5.12.
