The InterFET 2N4117 and 2N4117A Series of N-channel JFETs are targeted for ultra high input impedance applications for mid to high frequency designs. These JFETS offers a gate to source breakdown Voltage of either -40V, a low leakage of 0.25pA (typical) and comes in a through-hole TO-72 package which is hermetically sealed and suitable for military applications, also available as a bare die. The 2N4117 and 2N4117A JFETs have a drain to source saturation current of 0.03mA, low input capacitance of 2pF (typical), high input impedance and can be operated in a temperature range of -55°C to +125°C.

As with all InterFET products, the 2N4117 and 2N4117A JFET series are available for customisation to meet even the strictest application demands. The customisable features include unique test or review parameters, package style, binning options, channel configurations, multi-geometry and hybrid solutions and many others.

Typical applications for the 2N4117 and 2N4117A JFET series from InterFET include:

  • Low leakage input buffer
  • High frequency amplifier/buffer
  • Ultra high impedance pre-amplifier
  • Voltage controlled resistor
  • Current limiters and regulators
