BOSFET® Photovoltaic Relay
General Description
The Photovoltaic AC Relay (PVA) is a single-pole, nor-
mally open solid state replacement for electro-me-
chanical relays used for general purpose switching of
analog signals. 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 dielectrically isolated light emitting di-
ode (LED).
The PVA overcomes the limitations of both conven-
tional 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 voltages and miniaturization. These advan-
tages allow product improvement and design innova-
tions in many applications such as process control,
multiplexing, telecommunications, automatic test
equipment and data acquisition.
The PVA can switch analog signals from thermocouple
level to 300 volts peak AC or DC polarity. Signal fre-
quencies into the RF range are easily controlled and
switching rates up to 5kHz are achievable. The ex-
tremely small thermally generated offset voltages allow
increased measurement accuracies.
Unique silicon technology developed by International
Rectifier 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 protec-
tion functions. This section of the BOSFET chip utilizes
both bipolar and MOS technology to form NPN transis-
tors, P-channel MOSFETs, resistors, diodes and ca-
pacitors.
The photovoltaic generator similarly utilizes a unique
International Rectifier alloyed multijunction structure.
The excellent current conversion efficiency of this tech-
nique results in the very fast response of the PVA mi-
croelectronic power IC relay.
This advanced semiconductor technology has created
a radically new control device. Designers can now de-
velop switching systems to new standards of electrical
performance and mechanical compactness.
