Description

 

The 2N3819 is a low-cost, all-purpose JFET which offers good performance at mid-to-high frequencies. It features low noise and leakage and guarantees high gain at 100 MHz. The 2N3819 is designed for RF amplifier and mixer applications operating up to 450MHz, and for analog switching requiring low capacitance. Its TO-226AA (TO-92) package is compatible with various tape-and-reel options for automated assembly. For similar products in TO-206AF (TO-72) and TO-236 (SOT-23) packages, see the 2N4416/2N4416A/SST4416 data sheet.
