DESCRIPTION
APPEARANCE
The SMCJ5.0-170A or SMCG5.0-170A series of 1500 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.
IMPORTANT:
