PVA3055NPBF

Relay SSR 25mA DC-IN 0.05A 300V AC-DC-OUT 4Pin PDIP Tube

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 ’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 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 1.7 kHz are achievable. The extremely small thermally generated offset voltages allow increased measurement accuracy. These relays are packaged in 8-pin, molded DIP packages and available with either thru-hole or surface-mount “gullwing” leads, in plastic shipping tubes.
