DESCRIPTION
APPEARANCE
This Transient Voltage Suppressor (TVS) series for 1N6356 thru 1N6372 are
JEDEC registered selections for both unidirectional and bidirectional devices.
The 1N6356 thru 1N6364 are unidirectional and the 1N6365 thru 1N6372 are
bi-directional where they all provide a very low specified clamping factor for
minimal clamping voltages (VC) above their respective breakdown voltages
(VBR) as specified herein. They are most often used in protecting sensitive
components from inductive switching transients or induced secondary
lightning effects as found in lower surge levels of IEC61000-4-5 . They are
also very successful in protecting airborne avionics and electrical systems.
Since their response time is virtually instantaneous, they can also protect
from ESD and EFT per IEC61000-4-2 and IEC61000-4-4.

FEATURES
APPLICATIONS / BENEFITS
Unidirectional and bidirectional TVS series for thru-hole
mounting
Suppresses transients up to 1500 watts @ 10/1000 s
tclamping (0 volts to V(BR) min):
Unidirectional – Less than 100 pico seconds.
Bidirectional – Less than 5 nano seconds.
Working voltage (VWM) range 5 V to 45 V
Low clamping factor (ratio of actual VC/VBR): 1.33 @
full rated power and 1.20 @ 50% rated power
Hermetic sealed DO-13 metal package
Options for screening in accordance with MIL-PRF-19500
for JAN, JANTX, JANTXV, and JANS are also available
by adding MQ, MX, MV, SP prefixes respectively to part
