World's Largest Supplier of JFET Products

InterFET has the best Analog Front End (AFE) solutions in the industry. It is a digital world, but the interfaces are still analog. Getting the analog sensor interface back to the digital world with the lowest noise and the lowest power is where the JFET excels. InterFET has the widest JFET part offerings and is the worlds largest supplier of JFET Products. We have been delivering JFET solutions for over 35 years.

A compact and responsive company, we are well positioned to respond to our customers’ special product requirements, to develop marketable new products, and to strengthen and broaden our production and distribution of industry standard product types. InterFET continually pushes the performance limits of technology, without sacrificing acceptable manufacturing yields and the associated cost control advantages. Our product applications include component and sub-assembly computer circuitry, medical instrumentation and devices, test and measurement instrumentation for a variety of analog and digital applications, defense systems, air and spacecraft, geophysical exploration instrumentation, and consumer products.

Find Your Solutions

Find A Cross Reference Part

Electrical PCB

As the Leading provider of the industries broadest JFET product portfolio, InterFET prides itself on being able to cross any legacy or competitor JFET part number to an exact match or similar product family. 

Find Part By Electrical Characteristics

Oscilloscope Test Verification

Narrow down what part you need by determining the geometry type for your design. For example, if you need the lowest leakage part, search the Geometry Types table and find the N0001 geometry is the lowest leakage geometry. Next go to the JFET Master Table and sort on N0001 Geometry only.

Find Diodes and Current Regulators

Pico Amp Diodes (PAD) and Current Requlators. Diodes with less than 1pA of leakage. Constant current solutions that are very low noise.

Find Parts for Electrical Applications

Oscilloscope Waveform

JFETs for Electrical Applications: From low noise low frequency audio solutions to Voltage Controlled Resistors (VCR), InterFET has your application solution. 

Make Your Own Custom Part

Test Fixture

If you find an InterFET part that is close to your requirement but need to tweak a couple of parameters or add additional screening, InterFET can do that! Or maybe need a completely new design in the JFET space, InterFET does that.

Over 50% of our business is making custom solutions for our customers. Please contact us and let us know what you need.
