1N6138A – 1N6173A
Voidless Hermetically Sealed Bidirectional
Transient Voltage Suppressors
Qualified to MIL-PRF-19500/516
DESCRIPTION
This series of industry recognized voidless, hermetically sealed bidirectional Transient Voltage
Suppressors (TVS) are military qualified to MIL-PRF-19500/516 and are ideal for high-reliability
applications where a failure cannot be tolerated. They provide a working peak “standoff” voltage
selection from 5.2 to 152 Volts with a 1500 W rating for a 10/1000
µs
pulse. They are very robust
in hard-glass construction and use internal Category 1 metallurgical bonds for high reliability.
These devices are available as both a non-suffix part and an “A” version part involving different
voltage tolerances as described in the
nomenclature
section. These devices are also available in a
surface mount MELF package configuration.
Available on
commercial
versions

Steady-state power ratings with reference to ambient are for PC boards where thermal resistance from
mounting point to ambient is sufficiently controlled where T

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.
Breakdown Voltage: The voltage across the device at a specified current I
(BR)
in the breakdown region.
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.
Standby Current: The current through the device at rated stand-off voltage.
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.
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
.
