DESCRIPTION
APPEARANCE
Microsemi’s 200 kW bidirectional Transient Voltage Suppressor (TVS)
protects 120 volt ac airborne electronic equipment from harsh lightning
environments per RTCA/DO-160D Section 22 and is compatible with
Section 16 for 180 volt ac 100 ms highline surges. Microsemi also
offers a broad spectrum of other TVS products to meet your needs.

GRAPHS
NOTE: This PPP vs. 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 waveforms, derate power and current to 66% of that for
exponential decay.

INSTALLATION
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 3 through figure 6.
FIGURE 3
FIGURE 5
Figure

illustrates minimal 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”.
