Definition of "Breakdown Voltage" |
The voltage at which an insulator or dielectric ruptures, or at which ionization and conduction take place in a gas or vapor. / The voltage at which an insulator or dielectric ruptures, or at which ionization and conduction take place in a gas or vapor. The breakdown voltage is the maximum instantaneous voltage, including repetitive and non-repetitive transients, which can be applied across a junction in the reverse direction without an external means (circuit) of limiting the current. It is also the instantaneous value of reverse voltage at which a transition commences from a region of high small-signal impedance to a region of substantially lower small-signal impedance. / The breakdown voltage of an insulator is the minimum voltage that causes a portion of an insulator to become electrically conductive. / The Hamming weight of a string is the number of symbols that are different from the zero-symbol of the alphabet used. It is thus equivalent to the Hamming distance from the all-zero string of the same length. For the most typical case, a string of bits, this is the number of 1's in the string. In this binary case, it is also called the population count, popcount or sideways sum. It is the digit sum of the binary representation of a given number and the ℓ₁ norm of a bit vector. / (1) the reverse biased voltage across a device at which the current begins to dramatically deviate and increase relative to the current previously observed at lower voltages close to the breakdown voltage. This effect is attributed to avalanche or zener breakdown. It is usually specified at a predetermined value of current. |
