DESCRIPTION APPEARANCE
This series of industry recognized voidless-hermetically-sealed Unidirectional
Transient Voltage Suppressor (TVS) designs is military qualified to MIL-PRF-
19500/552 and are ideal for high-reliability applications where a failure cannot be
tolerated. They provid e a Working Peak “Standoff” Voltage selection from 5.0 to 51.6
Volts with 1500 W ratings. They are very robust in hard-glass construction and also
use an internal metallurgical bond identified as Category I for high reliability
applications. The 1500 W series is military qualified to MIL-PRF-19500/552. These
devices are also available in a surface mount MELF package configuration by adding
a “US” suffix (see separate data sheet for 1N6469US thru 1N6476AUS). Microsemi
also offers numerous other TVS products to meet higher and lower peak pulse power
and voltage ratings in both through-hole and surface-mount packages.

SYMBOLS & DEFINITI ONS
Symbol Definition
VBR Minimum Breakdown Voltage: The minimu m voltage the device will exhibit at a specified current.
VWM Working Peak Voltage: The maximum peak voltage that can be applied over the operating temperature range.
This is also referred to as Standoff Voltage.
ID Maximum Standoff Current: The maximum current that will flow at the specified voltage and temperature.
VC Maximum clamping voltage at specified IPP (Peak Pulse Current) at the specified pulse conditi ons.
PPP Peak Pulse Power: The peak power dissipation resulting from the peak impulse current IPP.
GRAPHS
Puls e time du ration (tp) is
defined as that point where
IP decays to 50% of peak
value (IPP).
Peak Value
IPP
Pulse current (IP) in percent of IPP
time (t) in milliseconds
FIG. 1 – Non-repetive peak pulse power rating curve FIG. 2 Pulse wave form for exponential surge
NOTE: Peak power defined as peak voltage times peak current for 10/1000 µs
