General Description
The Photovoltaic AC Relay (PVA) is a single-pole, nor-
mally open solid state replacement for electro-mechanical
relays used for general purpose switching of analog sig-
nals. It utilizes as an output switch a unique bidirectional
(AC or DC) MOSFET power IC termed a BOSFET. The
BOSFET is controlled by a photovoltaic generator of novel
construction, which is energized by radiation from a di-
electrically isolated light emitting diode (LED).
The PVA30 series combines very low solid state output
capacitance, very high off-state resistance and very fast
response. These Photovoltaic Relays are designed specifi-
cally to accurately switch low-level signals in high-perfor-
mance instrumentation systems.
The PVA overcomes the limitations of both conventional
and reed electromechanical relays by offering the solid
state advantages of long life, high operating speed, low
pick-up power, bounce-free operation, low thermal volt-
ages and miniaturization. These advantages allow product
improvement and design innovations in many applications
such as process control, multiplexing, telecommunica-
tions, automatic test equipment and data acquisition.
The PVA30 series can switch analog signals from thermo-
couple level to 300 volts peak AC or DC polarity. Signal
frequencies into the RF range are easily controlled and
switching rates up to 25kHz are achievable.
The extremely small thermally generated offset voltages
allow increased measurement accuracies. The critical out-
put semiconductors are completely shielded from the in-
fra-red radiation of the input LED. Therefore, photocurrents
in the output BOSFET are nonexistent and there is not an
output offset resulting from radiation from the input LED
drive.
Unique silicon technology developed by International Rec-
tifier forms the heart of the PVA. The monolithic BOSFET
contains a bidirectional N-channel power MOSFET output
structure. In addition, this power IC chip has input circuitry
for fast turn-off and gate protection functions. This section
of the BOSFET chip utilizes both bipolar and MOS tech-
nology to form NPN transistors, P-channel MOSFETs, re-
sistors, diodes and capacitors.
The photovoltaic generator similarly utilizes a unique Inter-
national Rectifier alloyed multijunction structure. The ex-
cellent current conversion efficiency of this technique re-
sults in the very fast response of the PVA microelectronic
power IC relay.
This advanced semiconductor technology has created a
radically new control device. Designers can now develop
switching systems to new standards of electrical perfor-
mance and mechanical compactness.
