Думаю, опираться лучше на этот фрагмент: "..... Although the silicon avalanche junction transient
voltage suppressor (SAJTVS) will first fail short in most
applications, there is always one transient event that will
cause it to open initially. In this case, the transient energy is
large and of short duration that the silicon chip itself
explodes.
When a TVS device does short, follow-on operating current
may cause the device to open. Fusing of the line is
recommended in all applications. ....."
