Series PVR33N & PbF

Microelectronic Power IC

Dual-Pole, Normally-Open

0-300V AC/DC, 165mA

General Description

The PVR33 Series AC/DC Relay is a dual-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 PVR33 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 PVR33 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 350Hz are

achievable. The extremely small thermally generated

offset voltages allow increased measurement

accuracies.

These relays are packaged in 16-pin, molded DIP

packages and available with thru-hole leads, in

plastic shipping tubes.
