1500 W LOW CLAMPING FACTOR
TRANSIENT VOLTAGE SUPPRESSOR
DESCRIPTION
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 (V
C
) above their respective breakdown voltages
(V
BR
) 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.

TVS devices are not typically used for dc power dissipation and are instead operated at or less than their rated standoff voltage
(V
WM
) except for transients that briefly drive the device into avalanche breakdown (V
BR
to V

region).

NOTE 1: TVS devices are normally selected according to the reverse “Stand Off Voltage” (V
WM
) which should be equal to or greater than the DC or
continuous peak operating voltage level.
* The minimum breakdown voltage as shown takes into consideration the + volt tolerance normally specified for power supply regulation on
most integrated circuit manufacturers data sheets. Similar devices are available with reduced clamping voltages where tighter regulated
power supply voltages are employed.
