DESCRIPTION

APPEARANCE

The Transient Voltage Suppressor (TVS) series for 1N5908 & 1N6267-1N6303A
are JEDEC registered selections for unidirectional devices. The popular series
of 1.5KE6.8-1.5KE400A 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.
