Introduction
New models with a wider range of characteristics provide an array of
solutions, meeting the needs of today’s high performance applications
The built-in Current Limit Function (CLR models) has many uses.
.
Traditionally used to clamp excessive over current fault conditions in
telecom equipment, this feature can also be used to good effect to
resist transient and short circuit conditions.
Our expanded range of MOS FET relays, Type G3VM, sets the
benchmark in Solid State Relays (SSRs). Products are manufactured
using the latest advances in automated production and include a
variety of improved construction technologies within the areas of the
input LED, PDA (Photo Diode Array used as a photocoupler) and
MOS FET chips used in the load switching circuit. As a result, further
reductions in package size and power requirements have been
achieved.
MOS FET relays are the ideal data and telecommunication solution
for line seizing, line switching, hook switching, Data Access Arrange-
ment (DAA) function, line transformer circuit control and other feature
phone functions. Central office applications require high reliability
and long life. Here the G3VM is ideal for use in the areas of Sub-
scriber Line Interfaces (SLICs) Multiplexers and Routers. In addition,
Local Area Networks (LANs) and Network Termination Units (NTUs)
including Set-Top Boxes (STBs) and Remote Metering Systems
(RMS) can take advantage of the G3VMs’ small size and low ON
resistance.
Combining the advantages of mechanical and solid state technology,
the new G3VM range gives you unprecedented capability to design.
All models featured include a double MOS FET load circuit, enabling
the designer complete versatility since it makes no difference
whether an AC or DC load in either direction is connected (Connec-
tion A). Thus, the MOS FET relay is a fully functional alternative to an
electromechanical relay with minimal additional drive circuitry.
Advances in performance and cost reduction enable MOS FET
relays to be considered as good alternatives to Reed Relays in appli-
cation areas such as security motion detectors (standard and anti-
mask PIRs), and Automated Test Equipment (ATE) probe cards.
