Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
82 words
An over-voltage clipping diode comprising a plurality of diode chips serially arranged in the same conduction direction, each of said diode chips being sandwiched between two distributor blocks of a material having a high thermal conductivity and a large thermal capacity with respect to the semi-conductive body of the respective diode chips, the thickness of the distributor blocks being larger than the thermal propagation length in the material for the pulses having the maximum time duration to be clipped by the diode.
Claim 2
Dependent Claim
82 words
An over-voltage clipping diode comprising a plurality of diode chips serially arranged in the same conduction direction, each of said diode chips being sandwiched between two distributor blocks of a material having a high thermal conductivity and a large thermal capacity with respect to the semi-conductive body of the respective diode chips, the thickness of the distributor blocks being larger than the thermal propagation length in the material for the pulses having the maximum time duration to be clipped by the diode.
Claim 3
Dependent Claim
16 words
An over-voltage clipping diode according to claim 1 wherein the distributor blocks are made of silver.
Claim 4
Dependent Claim
