Voltage Suppressor (TVS) Device
DESCRIPTION
These MRT100KP40A – MRT100KP400CA high reliability devices protect against dangerous
high-voltage, short term transients such as those caused the the secondary effects of lightning
per IEC61000-4-5 (see protection classes below) and RTCA/DO-160. They also protect
against voltage spikes caused by inductive load switching, induced RFI, and ESD or EFT per
IEC61000-4-2 and IEC61000-4-4. Clamping time is nearly instantaneous at < 5ns.

SYMBOLS & DEFINITIONS
Definition
Temperature Coefficient of Breakdown Voltage: The change in breakdown voltage divided by the change in
temperature that caused it expressed in %/°C or mV/°C.
Working Standoff Voltage: The maximum-rated value of dc or repetitive peak positive cathode-to-anode voltage that
may be continuously applied over the standard operating temperature.
Peak Pulse Power. The rated random recurring peak impulse power or rated nonrepetitive peak impulse power. The
impulse power is the maximum-rated value of the product of I
PP
and V
C
.
Breakdown Voltage: The voltage across the device at a specified current I
(BR)
in the breakdown region.
Standby Current: The current through the device at rated stand-off voltage.
Peak Impulse Current: The maximum rated random recurring peak impulse current or nonrepetitive peak impulse
current that may be applied to a device. A random recurring or nonrepetitive transient current is usually due to an
external cause, and it is assumed that its effect will have completely disappeared before the next transient arrives.
Clamping Voltage: The voltage across the device in a region of low differential resistance during the application of an
impulse current (I
PP
) for a specified waveform.
Breakdown Current: The current used for measuring Breakdown Voltage V

NOTES:
1.
Clamping voltage does not include any variable parasitic lead inductance effects observed during the 6.4
µs
rise time due
to lead length.
The maximum peak pulse current (I
PP
) shown represents the performance capabilities by design.
*Surge test screening is only performed up to 900 Amps (test equipment limitations).

NOTE:
This P

parts over a broad power spectrum using the guidelines illustrated in
MicroNote 104
on
www.microsemi.com.
Aircraft transients are described
with exponential decaying waveforms. For suppression of square-wave
impulses, derate power and current to 66% of that for the exponential
decay shown in Figure 1.
CORRECT
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 to 6. Figure 3
illustrates minimal parasitic inductance
with attachment at end of device.
Inductive voltage drop is across the 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”.
