Surface Mount 18,000 W Transient Voltage Suppressor Datasheet
1
Product Overview
These high-power, 18 kW-rated transient voltage suppressors in a surface-mount package are provided
with design features to minimize thermal resistance and cumulative heating. Typical applications include
lightning and automotive load dump protection. They are particularly effective at meeting the multi-
stroke lightning standard RTCA DO-160, section 22 for aircraft design. This efficient low-profile package
design is offered in standoff voltage selections (V
WM
) of 7 V to 200 V in either unidirectional or
bidirectional construction.
1.1

The following are key features of the MPLAD18KP7.0A—MPLAD18KP200CA devices:
Available in both unidirectional and bidirectional construction (bidirectional with CA suffix)
High reliability with wafer fabrication and assembly lot traceability
All parts surge tested
Low-profile surface mount package
Optional upscreening is available with various screening and conformance inspection options based
on MIL-PRF-19500. Refer to
Hirel Non-Hermetic Product Portfolio
brochure on our website for more
details on the screening options.

Peak Pulse Power vs. Pulse Time (see page
6)
)
Moisture classification is Level 1 with no dry pack required per IPC/JEDEC J-STD-020B
RoHS-compliant versions are available
3σ lot norm screening performed on standby current (I
D
)
AEC-Q101 qualified

Definition
The current used for measuring breakdown voltage V
(BR)
.
The current through the device at rated stand-off voltage.
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.
The voltage across the device at a specified current I
(BR)
in the
breakdown region.
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.
The maximum-rated value of dc or repetitive peak positive cathode-
to-anode voltage that may be continuously applied over the
standard operating temperature.
The change in breakdown voltage divided by the change in
temperature that caused it expressed in %/°C or mV/°C.

Notes:
1. Transient voltage suppressors are normally selected with reverse standoff voltage V
WM
, which should
be equal to or greater than the peak operating voltage.
2. Surge testing is performed to 1000 A due to equipment limitations.
