Vishay Siliconix U440 is a dual N-channel JFET designed for general-purpose amplification and switching applications. This through-hole component features a breakdown voltage of 25V and a maximum power dissipation of 500mW. The U440 exhibits a typical continuous drain current (Idss) of 6mA at 10V drain-source voltage with zero gate-source voltage. Input capacitance (Ciss) is specified at a maximum of 3pF at 10V drain-source voltage. The device operates reliably within an extended temperature range of -55°C to 150°C. The JFET is housed in a TO-71-6 package and is supplied in tubes. Applications for this component include signal processing and control circuits in industrial automation and test and measurement equipment.
