DESCRIPTION
APPEARANCE
This Transient Voltage Suppressor (TVS) series for 1N6373 thru 1N6389
are JEDEC registered selections for both unidirectional and bidirectional
devices. The 1N6373 thru 1N6381 are unidirectional and the 1N6382 thru
1N6389 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
CASE 1
instantaneous, they can also protect from ESD and EFT per IEC61000-4-2
and IEC61000-4-4.

(VWM) except for transients that briefly drive the device into avalanche breakdown (VBR to VC region).
