Introduction

JFE150 is a discrete JFET built using a modern high-performance analog bipolar process. The JFE150 delivers performance not available with older discrete JFET technologies. It offers excellent noise-power efficiency and flexibility, with quiescent current user-settable and outstanding noise performance for currents ranging from 50μA to 20mA. At a bias current of 5mA, the device achieves an input-referred noise of 0.8nV/√Hz, providing ultra-low noise performance with extremely high input impedance (>1TΩ). The JFE150 also features integrated diodes connected to independent clamp nodes, offering protection without the need for high-leakage, nonlinear external diodes. The JFE150 supports a high drain-to-source voltage of 40V, as well as gate-to-source and gate-to-drain voltages down to −40V. The device is rated for an operating temperature range of −40°C to +125°C and is available in 5-pin SOT-23 and SC70 packages.
