Data Sheet No. PD10051-D

Series PVA33N

Microelectronic Power IC

Single-Pole, Normally-Open

0-300V AC/DC, 150mA

General Description

The PVA33 Series AC Relay (PVA) is a single-pole,

normally open, solid-state replacement for

electromechanical relays used for general purpose

switching of analog signals. It utilizes International

Rectifier’s HEXFET power MOSFETs as the output

switches, driven by an integrated circuit photovoltaic

generator of novel construction. The output switch is

controlled by radiation from a GaAlAs light emitting

diode (LED), which is optically isolated from the

photovoltaic generator.

The PVA33 Series overcomes the limitations of both

conventional electromechanical and reed relays by

offering the solid state advantages of long life, fast

operating speed, low pick up power, bounce-free

operation, low thermal offset voltages and miniature

package. These advantages

allow

product

improvement and design innovations in many

applications such as process control, multiplexing,

automatic test equipment and data acquisition.

The PVA33 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 500Hz are

achievable. The extremely small thermally generated

offset voltages allow increased measurement

accuracies.

These relays are packaged in 8-pin, molded DIP

packages and available with either thru-hole or

surface-mount (“gull-wing”) leads, in plastic shipping

tubes.
