NOTE: This PPP versus time graph allows the
designer to use these parts over a broad power
spectrum using the guidelines illustrated in App
Note 104 on Microsemi’s website. Aircraft
transients are described with exponential
decaying waveforms. For suppression of
square-wave impulses, derate power and current
to 66% of that for exponential decay as shown in
Figure 1.

INSTALLATION
Correct
Wrong
TVS devices used across power
lines are subject to relatively high
magnitude surge currents and are
more prone to adverse parasitic
inductance effects in the mounting
leads. Minimizing the shunt path of
the lead inductance and their V= -
Ldi/dt effects will optimize the TVS
effectiveness.
Examples
of
optimum installation and poor
installation are illustrated in figures

parasitic
inductance with attachment at end
of device. Inductive voltage drop is
across input leads. Virtually no
“overshoot” voltage results as
illustrated with figure 4. The loss of
effectiveness in protection caused
by excessive parasitic inductance is
illustrated in figures 5 and 6. Also
see MicroNote 111 for further
information on “Parasitic Lead
Inductance in TVS”.

NOTE: The 1MHz damped oscillatory waveform (3) has an effective pulse width of 4 s. Equivalent peak pulse power at each of
the pulse widths represented in RTCA/DO-160E for waveforms 3, 4 and 5A (above) have been determined referencing Figure 1
herein as well as Application Notes 104 and 120 (found on Microsemi’s website) and are listed below.

Note: High current fast rise-time transients of 250 ns or less can more than triple the VC from parasitic inductance effects (V= -
Ldi/dt) compared to the clamping voltage shown in the Electrical Characteristics as also described in Figures 5 and 6 herein.
