General Description
The PVA30 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鈥檚 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 PVA30 Series combines very low solid-state output
capacitance, very high off-state resistance and very fast
response times. These Photovoltaic Relays are designed
specifically to accurately switch low-level signals in high-
performance instrumentation systems.
The PVA30 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 PVA30 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 1.7kHz 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 (鈥済ull-
wing鈥? leads, in plastic shipping tubes.
