The InterFET SMP5115 series of P-channel JFETs offers P0099F geometry, with a gate to source breakdown Voltage 30V and Low noise of 8nV/√Hz. This JFET series comes in a through-hole SOT23 package and is also available as a bare die. The SMP5115 JFET has a drain to source saturation current of -15mA and can be operated in a temperature range of -55°C to +125°C.

As with all InterFET products, the SMP5115 JFET series is 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 SMP5115 JFET series from InterFET include:

  • Analog switches
  • Choppers
