DESCRIPTION
APPEARANCE
The Transient Voltage Suppressor (TVS) series for 1N5908 & 1N6267-1N6303A
are JEDEC registered selections for unidirectional devices. The popular series of
1.5KE6.8-1.5KE400CA offers similar voltages with an extended voltage range
and also provides bidirectional options with a C or CA suffix. All have the same
high Peak Pulse Power rating of 1500 W and extremely fast response time. They
can protect from secondary lightning effects per IEC61000-4-5 and class levels
described herein as well as inductive switching environments and induced RF
protection. Since their response time is virtually instantaneous, they can also
protect from ESD and EFT per IEC61000-4-2 and IEC61000-4-4.
