SCOTTSDALE DIVISION
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 (SMCJ)
with the DO-214AB package for greater PC board mounting density or in a
Gull-wing design (SMCG) 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.
