1N6138AUS – 1N6173AUS
Voidless Hermetically Sealed Surface Mount
Bidirectional Transient Voltage Suppressors
Qualified to MIL-PRF-19500/516
DESCRIPTION
This surface mount series of industry recognized voidless, hermetically sealed, bidirectional
Transient Voltage Suppressor (TVS) designs 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 watt rating for a 10/1000 us
pulse. They are very robust in hard-glass construction and use internal Category 1 metallurgical
bonds for high reliability. These are also available as both a non suffix part and an “A” version part
involving different voltage tolerances as further described in the
nomenclature
section. These
devices are also available in axial-leaded packages for thru-hole mounting.

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
.
