Quad Capacitance
Capacitance of Schottky diode quads is measured using
an HP4271 LCR meter. This instrument effectively isolates
individual diode branches from the others, allowing ac‑
curate capacitance measurement of each branch or each
diode. The conditions are: 20 mV R.M.S. voltage at 1 MHz.
Avago defines this measurement as “CM”, and it is equiva‑
lent to the capacitance of the diode by itself. The equiva‑
lent diagonal and adjacent capaci‑tances can then be cal‑
culated by the formulas given below.
In a quad, the diagonal capacitance is the capacitance be‑
tween points A and B as shown in the figure below. The
diagonal capacitance is calculated using the following
formula
The equivalent adjacent capacitance is the capacitance
between points A and C in the figure below. This capaci‑
tance is calculated using the following formula
This information does not apply to cross‑over quad di‑
odes.
