LC6.5 – LC170A
1500 Watt Low Capacitance
Transient Voltage Suppressor
DESCRIPTION
This hermetically sealed Transient Voltage Suppressor (TVS) product family includes a
rectifier diode element in series and in the opposite direction. This allows it to present a very
low (< 100 pF) capacitance to the system it is protecting (see
Figure 2).
The low capacitance
of these devices makes them particularly useful for protecting lines carrying high frequency
signals. They are also useful in protecting from the secondary effects of lightning in airborne
avionics per IEC61000-4-5, RTCA/DO-160G, and ARINC 429. If bidirectional transient
capability is required, two of these low capacitance TVS devices may be used in parallel in
opposite directions (anti-parallel) for complete ac protection as shown in
Figure 4.

FEATURES
Unidirectional low-capacitance TVS series for flexible thru-hole mounting.
For bidirectional applications, use two in anti-parallel (see
Figure 4).
Suppresses transients up to 1500 watts @ 10/1000 µs (see
Figure 1).
Clamps transients in less than 100 pico seconds (theoretical for unidirectional).*
Working voltage (V
WM
) range 6.5 V to 170 V.
5% and 10% tolerance versions available.
Hermetic sealed DO-13 metal package.
Screening options available in reference to MIL-PRF-19500.
(See
Part Nomenclature
for all available options.)
RoHS compliant versions available.
