What InterFET does
InterFET Corporation is a privately held specialty semiconductor company founded in 1982 as a spinoff from Texas Instruments' Silicon Small Signal Group and headquartered in Richardson, Texas. The company designs, manufactures, and supplies Junction Field Effect Transistors (JFETs) and related analog front-end devices, claiming the position of the world's largest supplier of standard JFET products with a portfolio of more than 566 standard parts across 14+ proprietary geometry types and multiple package formats (TO-18, TO-72, TO-92, SOT-23, SOIC-8, and bare die).
The core technology centers on JFET-based analog signal conditioning, with proprietary geometry designs that yield differentiated performance: the N0001H geometry enables PicoAmp Diodes with leakage below 200 femto-amps at 20V; the N3600 geometry is positioned as the industry's lowest-noise JFET; the N0042 supports 300-400V breakdown; and the N0014 targets ultra-low-noise applications. Supporting offerings include Current Regulator Diodes, SPICE/LTspice modeling tools with GMin parameter support, and JAN-equivalent / MIL-PRF-19500 qualified variants for military and aerospace use. Manufacturing takes place in a purpose-built 18,000+ square foot facility that houses wafer probe, metal case assembly, and MCM-C manufacturing and test operations.
The business model is hardware sales of both standard catalog parts and custom JFET solutions, with over 50% of revenue derived from custom work (custom binning, matched pairs, hybrid solutions, hi-reliability screening, and bespoke multi-geometry designs). Pricing is quote-based and not publicly disclosed, with minimum order quantities of $750 for standard products and $3,000 for custom products on Net 30 terms. InterFET reaches customers through a multi-channel go-to-market combining direct factory sales, global distribution via Mouser and DigiKey, regional specialty distributors (Rhopoint, Euromip, Cornes, MetaTech), and a network of manufacturer representatives across North America, Europe, and Asia. End markets include test and measurement instrumentation, medical instrumentation, audio equipment, military/aerospace, industrial sensor systems, and consumer products.
