1 Form A Photovoltaic Relay in a mod. 8-pin SMT Package 100 V, 375 mA single pole Photovoltaic Relay in a mod. 8-pin SMT. This normally open solid-state relay can replace electromechanical relays used for general purpose switching of analog signals. The PVA13 Series offers long life, fast operating speed, low pick up power, bounce-free operation, low thermal offset voltages and miniature package. In addition analog signals can be switched from thermocouple level to 100 Volts peak AC or DC.
