High Voltage Solid State Relays
General Information
FEATURES
DESCRIPTION
Siemens Solid State Relays (SSRs) are miniature, optically-coupled relays
with high-voltage MOSFET outputs. The relays are capable of switching ac
or dc loads from as little as nanovolts to hundreds of volts. Likewise, the
relays can switch currents in the range of nanoamps to hundreds of milli-
amps. The MOSFET switches are ideal for small signal switching and are
primarily suited for dc or audio frequency applications.
• 3750 Vrms or 5300 Vrms I/O isolation
• Current-limit protection built-in
• Linear ac/dc operation
• High-reliability monolithic receptor
• Extremely low leakage current (pA)
• High contact off-impedance (GW)
• Low power consumption (1 mW—12 mW)
• Very low switch offset (typically 0.1 mV)
• Logic compatible
Siemens offers integrated current limiting on many of its relays. If load
current through the relay exceeds the rated value, the relay clamps the
current at a predefined value. If the excessive load current persists, the
limiting circuit has a foldback feature to minimize relay power dissipation.
The current-limit circuit has a multitude of uses. It can be used in tele-
phony to clamp excessive currents emanating from lightning strikes and/
or power-main crosses or in instrumentation and industrial application to
squelch transients from reactive loads. The current-limit circuit also
provides short-circuit protection in power-feed applications.
• Clean, bounce-free switching
• Built-in 1 Form C break-before-make
• High surge capability
• Insensitive to dv/dt
• Surface mountable
• Compatible with UL1459 and FCC 68.302
• UL recognized
• CSA certified
• BABT certificate of recognition to BS6301
The SSRs feature a monolithic output die that minimizes wire bonds and
permits easy integration of high-performance circuits such as current
limiting in normally-open switches. The output die contains all the neces-
sary circuitry to perform a relay function, including the photodiode
receptor array, turn-on and turn-off control circuitry, and the MOSFET
switches. The optically-coupled input is controlled by a highly efficient
GaAlAs infrared LED.
BENEFITS
• Long life
• Maintenance free
• Current-limit SSRs can sustain
repeated faults without damage
Siemens SSRs are available in a 6- or 8-pin through-hole DIP or in gull-
wing surface-mount packages. Some parts are also offered in 8- or 18-pin
small-outline packages (SOPs). The SOPs are size and height compatible
with PCMCIA Type 2 cards. A 0.4 mm distance through insulation spacing
is also available on “H” suffix coded parts. Refer to the Parts Coding
section for a more in-depth description of these parts.

• Immune to environmental hazards
such as salt, dirt, and humidity
• No arcing
• No mounting restrictions
• Preapproved for DAA applications
• High reliability
• Easily configured in series or in parallel
for increased voltage or current
