U309 - N-Channel JFET

InterFET

Download the U309 datasheet PDF. This datasheet also covers the U308 variant, as both devices belong to the same n-channel jfet family and are provided as variant models within a single manufacturer datasheet.

General Description

The -25V InterFET U308 and U309 are targeted for higher gain VHF amplifiers, mixers, and oscillators.

Gate leakages are typically less than 10pA at room temperatures.

Key Features

InterFET N0072L Geometry.
Low Noise: 2 nV/√Hz Typical.
Low Ciss: 4pF Typical.
RoHS Compliant.
SMT, TH, and Bare Die Package options.
