Series PVR33

Microelectronic Power IC

Dual-Pole, 180mA, 0-300V AC/DC

General Description

The PVR33 Photovoltaic Relay is a dual-pole, normally

open solid state replacement for electro-mechanical

relays. 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 PVR overcomes the limitations of reed 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 PVR can switch analog signals from thermo-

couple level to 300 volts peak AC or DC polarity.

Signal frequencies into the RF range are easily con-

trolled and switching rates up to 5kHz are achiev-

able. The extremely small thermally generated offset

voltages allow increased measurement accuracies.

Unique silicon technology developed by International

Rectifier forms the heart of the PVR. 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

PVR microelectronic power IC relay.

This advanced semiconductor technology has cre-

ated a radically new control device. Designers can

now develop switching systems to new standards of

electrical performance and mechanical compactness.
