DESCRIPTION
Microsemi’s 100 kW Transient Voltage Suppressors (TVSs) are designed
for aircraft applications requiring high power transient protection with a
comparatively small axial-leaded package size. This includes various
threats such as “Waveform 4” at 6.4/69 µs per RTCA/DO-160E Section 22.
It is also available with screening in accordance with MIL-PRF-19500 or
avionics screening as described in the Features section herein. It may also
be optionally acquired with RoHS Compliant (annealed matte-Tin finish)
www.DataSheet4Uw.ciothm an e3 suffix added to the part number. Microsemi also offers a broad
spectrum of other TVSs to meet your needs.
IMPORTANT: For the most current data, consult MICROSEMI’s website: http://www.microsemi.com

1. For bidirectional construction, indicate a CA suffix (instead of A) after the part number
2. Clamping voltage does not include any variable parasitic lead inductance effects observed during the 6.4 µs rise time due to lead length.
3. The Maximum Peak Pulse Current (IPP) shown represents the performance capabilities by design.
* Surge test screening is only performed up to 900 Amps (test equipment limitations).
4. Part numbers in bold italics are preferred devices.

NOTE:GTRhAisPPHPSP 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 shown in Figure 1.

FIGURE 3
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 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”.
