Available
1500 Watt Unidirectional and Bidirectional
Transient Voltage Suppressor
DESCRIPTION
The popular Transient Voltage Suppressor series of 1.5KE6.8 – 1.5KE400CA along with its
upscreening options offer an extended voltage range and also provide a wide variety of
commercial, high reliability, RoHS and bidirectional options. All have the same high peak
pulse power rating of 1500 W and extremely fast response time. They can protect from
secondary effects of lightning per IEC61000-4-5 and the class levels as shown below as well
as voltage transients from inductive switching and RFI. Since their response time is virtually
instantaneous, they also protect from ESD and EFT per IEC61000-4-2 and IEC61000-4-4.

SYMBOLS & DEFINITIONS
Definition
Breakdown Current: The current used for measuring breakdown voltage V
(BR)
.
Breakdown Voltage: The voltage across the device at a specified current I
(BR)
in the breakdown region.
Working Standoff Voltage: The maximum-rated value of dc or repetitive peak positive cathode-to-anode voltage that
may be continuously applied over the standard operating temperature.
Clamping Voltage: The voltage across the device in a region of low differential resistance during the application of an
impulse current (I
PP
) for a specified waveform.
Peak Impulse Current: The maximum rated random recurring peak impulse current or nonrepetitive peak impulse
current that may be applied to a device. A random recurring or nonrepetitive transient current is usually due to an
external cause, and it is assumed that its effect will have completely disappeared before the next transient arrives.
Peak Pulse Power. The rated random recurring peak impulse power or rated nonrepetitive peak impulse power. The
impulse power is the maximum-rated value of the product of I
PP
and V
C
.
Standby Current: The current through the device at rated stand-off voltage.

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 continuous 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 types having V
WM
of 8 volts and under, the I
D
leakage current is doubled. Also for bidirectional parts, the capacitance
will be half 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.
