1.5KE6.8
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.
IMPORTANT: For the most current data, consult MICROSEMI’s website: http://www.microsemi.com
FEATURES
APPLIC ATIONS / BENEFITS
• Economical TVS series for thru-hole mounting

NOTES: 1. Normal selection criteria for TVS devices is by rated stand-off voltage (VWM) and should be equal or greater than dc or continuous peak
operating voltage.
2. TVS devices are tested to maximum peak pulse current (IPP) with clamping voltage monitored. This surge capability is one of the most
significant electrical characteristics of the device and should be considered as part of customer quality inspections.
3. For Bidirectional part number add C or CA as suffix (e.e., 1.5KE33C or 1.5KE33CA). For Bidirectional types having VWM of 8 volts and
under, the ID leakage current is doubled. 1N62XX or 1N5908 not available as Bidirectional. For Bipolar capacitance will be .5 that shown in
Fig. 2 for zero bias.
4. For unidirectional, the forward voltage (VF) is 3.5 volts maximum at 100 Amps peak for 8.3 ms half-sine wave.
