SURFACE MOUNT 3000 Watt
Transient Voltage Suppressor
DESCRIPTION
The SMLJ5.0-170A or SMLG5.0-170A series of 3000 W Transient Voltage
Suppressors (TVSs) protects a variety of voltage-sensitive components
from destruction or degradation. It is available in J-bend design (SMLJ)
with the DO-214AB package for greater PC board mounting density or in a
Gull-wing design (SMLG) in the DO-215AB for visible solder connections.
Selections include unidirectional and bidirectional. They can protect from
secondary lightning effects per IEC61000-4-5 and class levels defined
herein, or for inductive switching environments and induced RF protection.
Since their response time is virtually instantaneous, they can also be used
in protection from ESD and EFT per IEC61000-4-2 and IEC61000-4-4.

For Bidirectional device types indicate a C or CA suffix after the part number. (i.e.: SMLG170CA or
SMLJ170C). Bidirectional capacitance is half that shown in Figure 4 at zero volts.
Microsemi Corp’s SML series (3000W) surface mountable packages are designed specifically for transient
voltage suppression. The wide leads assure a large surface contact for good heat dissipation, and a low
resistance path for surge current flow to ground. These high-speed transient voltage suppressors can be
used to effectively protect sensitive components such as integrated circuits and MOS devices.
