1N6267 thru 1N6303A
1.5KE6.8 thru 1.5KE400A
Unidirectional & Bidirectional
Transient Voltage Suppressors
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.

FEATURES
APPLICATIONS / BENEFITS
Economical TVS series for thru-hole mounting
Available in both Unidirectional and Bidirectional (add
C or CA suffix for bi-directional)
Voltages from 6.8 to 400 V Breakdown (VBR)
Suppresses transients up to 1500 watts @ 10/1000 µs
(see Figure 1)
Fast response
Options for screening in accordance with MIL-PRF-
19500 for JAN, JANTX, JANTXV, and JANS are
available by adding MQ, MX, MV, or MSP prefixes
respectively to part numbers.
