TYPICAL RESULTS
Obtaining meaningful results with the AVR-EB2A-B requires care, experience, and an
understanding of diode transient behavior and the impact of inductive and capacitive
parasitics. To assist the user, typical results for commercially available diodes are
provided below. The user should be able to reliably duplicate these results.
1N4148 RESULTS
The 1N4148 is a common high-speed low-current switching diode, whose specification
are specified in the military “slash sheet” MIL-PRF-19500/116R . This sheet calls for a
maximum t
RR
of 5 ns when measured with I
F
= +10 mA and I
R
= -10 mA, measuring t
RR
at -1 mA. Using the AVR-EB2A-B under these conditions, the following waveform is
obtained:
The measured t
RR
is 2.8 ns, well below the maximum specified value of 5 ns. The
vertical scale of 20 mV/div corresponds to a device current scale of 4 mA / div. Some
ringing is observed, due to transmission line reflections. These are unavoidable.
