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.

FEATURES

? Economical surface mount TVS design in both J-bend

or Gull-wing terminations with fast response

? Available in both Unidirectional and Bidirectional

construction with a C or CA suffix

? Selections for 5.0 to 170 volts standoff voltages (VWM)

? Optional 100 screening for avionics grade is

available by adding MA prefix to part number for

added 100 temperature cycle -55oC to +125oC (10X)

as well as surge (3X) and 24 hours HTRB with post

test VZ & IR (in the operating direction for unidirectional

or both directions for bidirectional)

? Options for screening in accordance with MIL-PRF-

19500 for JANTX are available by adding MX prefix to

the part number.

? Axial-lead packages for thru-hole mounting available

as 5KP5.0–110A with 5000 W rating (consult factory

for other surface mount options)

? RoHS Compliant devices available by adding e3 suffix

? Moisture classification is Level 1 with no dry pack

required per IPC/JEDEC J-STD-020B
