General Description
PVA33 Features
The Photovoltaic AC Relay (PVA) is a single-pole, normally open solid state replacement for electro-mechanical 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 diode (LED).
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 voltages and miniaturization. These advantages allow product improvement and design innovations 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 frequencies into the RF range are easily controlled and
switching rates up to 5kHz are achievable. The extremely 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 protection functions. This section of the BOSFET chip utilizes
both bipolar and MOS technology to form NPN transistors, P-channel MOSFETs, resistors, diodes and capacitors.
The photovoltaic generator similarly utilizes a unique
International Rectifier alloyed multijunction structure.
The excellent current conversion efficiency of this technique results 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
performance and mechanical compactness.
