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.
IMPORTANT: For the most current data, consult MICROSEMI's website:

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 (V
BR
)
Suppresses transients up to 1500 watts @ 10/1000 s
(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.
Surface mount equivalent packages are available as
SMCJ5.0 - SMCJ170CA or SMCG5.0 - SMCG170CA
(consult factory for other surface mount options)
Moisture classification is Level 1 with no dry pack
required per IPC/JEDEC J-STD-020B

NOTES: 1. Normal selection criteria for TVS devices is by rated stand-off voltage (V
WM
) and should be equal or greater than dc or continous peak
operating voltage.
2. TVS devices are tested to maximum peak pulse current (I
PP
) 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 V
WM
of 8 volts and
under, the I
D
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 (V
F
) is 3.5 volts maximum at 100 Amps peak for 8.3 ms half-sine wave.
