General Description
PVA13 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 100 volts peak AC or DC polarity. Signal frequencies into the RF range are easily controlled and switching
rates up to 2kHz 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, Pchannel 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.
