General Description

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 construc-

tion, 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 frequen-

cies 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, 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 microelec-

tronic 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.
