Advantages over mechanical relays
Most of the relative advantages of solid state relays over
electromechanical relays are common to all solid-state devices when
compared to electromechanical devices.
Inherently smaller and slimmer profile than mechanical relay of
similar specification, allowing tighter packing. (If desired may
have the same "casing" form factor for interchangeability.)
Totally silent operation.
SSRs switch faster than electromechanical relays; the switching
time of a typical optically coupled SSR is dependent on the time
needed to power the LED on and off - on the order of microseconds
to milliseconds.
Increased lifetime, even if it is activated many times, as there
are no moving parts to wear and no contacts to pit or build up
carbon.
Output resistance remains constant regardless of amount of use.
Clean, bounceless operation.
No sparking, allows it to be used in explosive environments, where
it is critical that no spark is generated during switching.
Much less sensitive to storage and operating environment factors
such as mechanical shock, vibration, humidity, and external
magnetic fields.
Disadvantages
Voltage/current characteristic of semiconductor rather than
mechanical contacts:
When closed, higher resistance (generating heat), and increased
electrical noise
When open, lower resistance, and reverse leakage current (typically
μA range)
Voltage/current characteristic is not linear (not purely
resistive), distorting switched waveforms to some extent. An
electromechanical relay has the low ohmic (linear) resistance of
the associated mechanical switch when activated, and the
exceedingly high resistance of the air gap and insulating materials
when open.
Some types have polarity-sensitive output circuits.
Electromechanical relays are not affected by polarity.
Possibility of spurious switching due to voltage transients (due to
much faster switching than mechanical relay)
Isolated bias supply required for gate charge circuit
Higher transient reverse recovery time (Trr) due to the presence of
the body diode
Tendency to fail "shorted" on their outputs, while
electromechanical relay contacts tend to fail "open".
